Q

Negative feedback

A

a type of regulation in biological systems in which the end product of a process in turn reduces the stimulus of that same process.

Q

describe the importance of negative feedback mechanism
in the maintenance of body internal environment stable (homeostasis)

A

Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value, of 98.6 ∘ F 98.6\,^\circ\text F 98.

Q

describe hyper/hypothyrodism with negative feedback

A

Hypothyroidism, on the other hand, happens due to inadequate thyroid hormone production. In primary hyperthyroidism, the thyroid produces large amounts of T3 and T4, which, through negative feedback inhibition, suppress TSH secretion from the anterior pituitary.

20
Q

tissue

A

group of cells with similar structure and function

21
Q

Four types of body tissues:

A

Epithelial

Connective

Muscle

Nerve

22
Q

Epithilial tisse is found on

A

Found on surfaces as either coverings (outer surfaces) or linings (inner surfaces). Many

epithelial tissues are capable of secretion (glands).

23
Q

describe types of epithilial tissues and their functions.

Simple squamous

Stratified squamous

Transitional Cuboidal

Cuboidal

Columnar

Ciliated

A
  • Simple squamous: one layer of flat cells
    1. Alveoli (gas exchange)

Capillaries (exchanges of materials)

  • Stratified squamous: many layers of cells, lower layer undergoes mitosis
    1. ​​Epidermis, Lining of esophagus, vagina (barrier to pathogens)Transitional
  • Transitional: Many layers of cells; surface cells change from rounded to flat
    1. Lining of urinary bladder (permits expansion without tearing the lining)
  • Cuboidal: one layer of cubed shaped cells
    1. Thyroid gland (secretes thyroxine) Salivary glands (secrete saliva) Kidney tubules (reabsorption)
  • Columner:One layer of column-shaped cells
1. Stomach (secretes gastric juice)
 Small intestine (secretes enzymes and absorption, microvilli)
  • Ciliated:One layer of columnar cells with cilia on their free surfaces
1. Ttrachea (sweeps mucus and dust to the pharynx)
 Fallopian tube (sweeps ovum toward uterus)
24
Q
  1. GLANDS:
  2. Unicellular glands:
A
  1. cells or organs that secrete chemicals that has a function either at that site (exocrine) or at a more distant site (endocrine and hormones).
  2. Goblet cells found in the lining of the respiratory and digestive tracts. Their secretion is mucus.
25
Q

Multicellular Glands include…

A

Exocrine with ducts (tubes):

eg, salivary glands, sweat glands

gastric glands

Endocrine glands: ductless, hormones for target organs.

eg, thyroid gland adrenal gland

pituitary gland

26
Q

which organ has both edocine and exocrine glands?

A

pancreas

Exocrine: digestive enzymes to duodenum

Endocrine: insulin and glucagon

27
Q

CONNECTIVE TISSUE (cells + matrix) includes…

A

Areolar, adipose, fibrous, and elastic tissue, blood, bone, and cartilage

28
Q

Connetive tissure matrix:

A

  • Location;Attached to bones. Movements and produces heat
  • Effects of nerve impulse: voluntary

  • bring about contraction or regulate the rate of contraction (involuntary)

Cardiac

  • branched cells with faint straitions and one nucleus each
  • walls of the chambers of the heart–pumpd blood

regulate only the rate of contraction

32
Q

Nerve Tissue includes

Q

Nerve tissue of

CELL BODY

what is the structure ans function?

A

Structure: -contains the nucleus

-Function: regulates the functioninf of the neuron

34
Q

Nerve tissue

AXON

A

Structure: cellular process (extention)

Function: carries impulses away from the cell body

35
Q

Nerve tissue

DENTRITES

A

structure: cellular process (extention)

Function: carries impulses toward the cell body (dendrodentritic synapses

36
Q

Nerve tissue

SYNAPSE

A

structure: space between axon of one neuron and the dendrite or cell body of the next neuron’
function: transmits impulses from one neuron to others

37
Q

nerve tisse

NEUROTRANSMITTERS

A

structures: chemicals released by axons
function: transmits impulses across synapses

38
Q

nerve tisse

Neuroglia

A

structure: specialized cells in the central nervous system
function: form myelin sheaths and other functions

39
Q

nerve tissue

SCHWANN CELLS

A

STRUCTURE: specialized cells in the perpheral nervous system

function: form the myelin sheaths around neurons

40
Q

definition of body memebrane and the two types

A

sheets of tissues that cover or line surfaces or that separate

organs or parts (lobes) of organs from one another.

  1. Epithelial membranes
  2. Connective tissue membranes.
41
Q

what are the types of epithelial membranes?

A

serous: simple squamous epithelium.

Location and names:

Pleural membranes; parietal pleura, visceral pleura, serous fluid

Pericardium (pericardial membrane): Parietal pericardium (lines the fibrous pericardium) Visceral pericardium, Serous fluid

Peritoneum: Parietal; Visceral; Fluid

mucous:line respiratory, digestive, urinary, and reproductive tracts. The mucus secreted by these membranes keeps the lining epithelial cells moisturized.
