Q

Define Homeostasis

A

Homeostasis describes the process by which biological systems maintain a stable internal environment despite external changes. It a state of dynamic equilibrium, regulatory mechanisms detect deviations from a set point to bring the system back into equilibrium.

Q

Explain the types of homeostatic Regulation

A

intrinsic regulation / auto-regulation
automatic response in a cell tissue or organ to an environmental change. Organ maintains homeostasis within itself. Is Fast but limited.

heart controls heart rate -> stretch receptors in heart -> nerve / electrical impulses -> sinoatrial node releases electrical impulses -> received by cardiac muscle to adjust heart beast.

extrinsic regulation
response controlled by nervous (blood pressure) and endocrine system (blood glucose). Response of nervous system is fast. Endocrine system slower.

Blood pressure -> baroreceptors in blood vessels walls detect changes send signal to the brain -> received by medulla oblongata -> sends nervous signals through the autonomic nervous system -> muscles in blood vessel wall adjust diameter

Blood glucose -> glucose-sensing receptors in the pancreas detect chantes in blood/glucose -> In response beta cells in pancreas secrete insulin -> muscle and liver respond to insulin either increasing or decreasing glucose storage.

Q

What does a homeostatic regulatory mechanism consist of?

A
  1. receptor: receives the stimulus
  2. control center: process the signal and sends instructions
  3. effector: carries out instructions

regulation limits fluctuations to keep them close to a set point

Q

Two types of feedback

A

positive Feedback
response of the effector negates the stimulus. Body is brought back into homeostasis. Normal range maintained.

temperature regulation / blood pressure regulation

negative feedback
Initial stimulus produces a response that amplifies the original change in conditions. Body is brought out of homeostasis. Normal range is not maintained.

blood clotting / childbirth

Feedback Loop
Stimulus -> sensor -> control center -> effector

Q

Define dynamic equilibrium

A

Dynamic equilibrium refers to a state of balance in a system where ongoing processes occur at equal rates, resulting in no overall change in the system. It involves continuous movement and exchange, but the system remains stable because the rates of forward and backward reactions or processes are equal.

In terms of homeostasis

refers to a state where internal conditions within an organism are maintained within a narrow and optimal range despite external fluctuations, it is a state of continual adaptation.

76
Q

define serous membrane, give function, name sub layers

A

serous membrane

a mesothelial tissue which lines certain internal cavities of the body, forming a smooth, transparent, two-layered membrane lubricated by a fluid derived from serum

composed of simple squamous epithelium resting on layer of areolar connective tissue (subserous fascia)

parietal layers
line the walls of the body cavity

visceral layers
cover the organs -> the viscera

between the parietal and visceral layers is a very thin fluid-filled space called the serous space

the reduce friction between organs and cavity wall and provide cushioning against mechanical shocks.

77
Q

Name Three Serous Cavities

A

Pleura
surrounds the lungs in the pleural cavity and reduces friction between the lungs and the body wall.

pericardium

The pericardium is a double-walled sac that surrounds the heart and the roots of the great vessels (aorta, pulmonary trunk, superior vena cava, inferior vena cava). It provides protection to the heart and anchors it in place within the thoracic cavity

Fibrous Pericardium: The outer layer of the pericardium is tough and fibrous. It is composed of dense connective tissue and helps protect the heart and prevent overdistension.

Serous Pericardium: The inner layer of the pericardium is a thin, double-layered membrane consisting of:
Parietal Layer parietal pericardium: This lines the inner surface of the fibrous pericardium.
Visceral Layer (Epicardium) visceral pericardium: This layer adheres closely to the surface of the heart (epicardium) and is also known as the epicardium when referring to the outermost layer of the heart itself.

pericardial cavity

This is the space between the two layers of the serous pericardium (parietal and visceral layers). It contains a small amount of fluid known as pericardial fluid, which lubricates the surfaces of the heart as it moves within the pericardium during each heartbeat.

peritoneum
The peritoneum refers to a serous membrane that lines the abdominal cavity and covers the abdominal organs.
It consists of two layers:
Parietal peritoneum: This layer lines the walls of the abdominal cavity.
Visceral peritoneum: This layer covers the abdominal organs (viscera).

peritoneal cavity
The peritoneal cavity is the space between the parietal and visceral layers of the peritoneum.
It contains a small amount of serous fluid, known as peritoneal fluid, which allows the abdominal organs to slide against each other and the abdominal wall without friction during movements such as digestion and breathing.

When we refer to the "pleural cavity," "pericardial cavity," or "peritoneal cavity," we are specifically referring to the space between the visceral and parietal layers of the respective serous membranes (pleura, pericardium, peritoneum). These cavities contain a small amount of serous fluid, which lubricates the membranes and reduces friction during movements of the organs or structures they surround.
78
Q

79
Q

Name and describe parts of Thoracic Cavity

A

right and left plura

Contain the right and left lung. Serous membrane. Visceral pleura layer forms the surface of the lungs. Parietal pleura lines the inside of the rib cage. Pleural fluid fills the pleural cavity.

Mediastinum
space between the two plural cavities. Upper portion filled with blood vessels, trachea, esophagus, and thymus. Lower portion contains pericardium

pericardium
contains the heart. Serous membrane. Visceral pericardium layer of membrane forms the surface of the heart. Pericardial fluid fills pericardial space.

80
Q

Name and describe subcavities of the abdominopelvic cavity

A

abdominopelvic cavity can be divided into the abdominal and pelvic cavities. There is no physical barrier between the two cavities.

abdominal cavity
- contains digestive organs

The peritoneum is within the abdominal cavity. It is a serous membrane. The parietal peritoneum lines the cavity wall. The visceral peritoneum is called the mesentery at points where it forms a translucent membrane.

pelvic cavity
contains reproductive organs, rectum, and bladder

81
Q

define mesentery

A

double layer of visceral peritoneum attaches the intestines to the posterior abdominal wall. Holds intestines together

82
Q

retroperitoneal space: location, organs

A

Anatomical space posterior the peritoneam. Organs within retroperitoneal have peritoneum on the anterior side only. Structures that are not suspended by mesentary in the abdominal cavity and that lie between the parietal peritoneum are retroperitoneal.

contains: pancreas, kidney, ureters, and parts of digestive tract (ascending / descending colon, duodenum)

83
Q

Parts of a cell
11

A
  1. Cilia: Hair-like structures on the surface of some cells that move fluid, mucus, or cells over their surface.
  2. Lysosome: An organelle containing digestive enzymes that break down waste materials and cellular debris.
  3. Centrioles: Cylindrical structures that help organize the assembly of microtubules during cell division.
  4. Microtubules: Hollow tubes of protein that provide structural support and play a role in cell movement and division.
  5. Golgi apparatus: An organelle that modifies, sorts, and packages proteins and lipids for storage or transport out of the cell.
  6. Smooth Endoplasmic Reticulum: A network of tubular membranes involved in lipid synthesis and detoxification processes.
  7. Mitochondria: Organelles that produce energy (ATP) through cellular respiration.
  8. Rough Endoplasmic Reticulum: A network of membranes with ribosomes attached, involved in protein synthesis and processing.
  9. Cytoplasm: The jelly-like substance within a cell, excluding the nucleus, that contains organelles and is the site of most cellular activities.
  10. Nucleolus: A dense region within the nucleus where ribosomal RNA (rRNA) is produced and ribosome assembly begins.
  11. Chromatin: A complex of DNA and proteins in the nucleus that condenses to form chromosomes during cell division.
  12. Nucleus: The membrane-bound organelle that contains the cell’s genetic material and controls its activities.
84
Q

Name The Three Membrane Types

A

Q

Define situs inversus

A

is a congenital condition in which the major visceral organs are reversed or mirrored from their normal positions.

In individuals with situs inversus, the heart, liver, stomach, spleen, and other organs are located on the opposite side of the body compared to their usual positions.

For example, the heart, which is typically on the left side of the chest, is located on the right side in a person with situs inversus.

99

100
Q

define an eponym

A

An eponym is a word or phrase that derives from the name of a person, often the discoverer or inventor of a concept, technique, device, or disease.

The trend to replace eponyms with more descriptive names arises for several reasons:
- increase clarity
- precision
- and objectivity
