Homeostasis
Stay the same
Homeo
Means to stop
Stasis
Monitors the body temperature by detecting stimuli
Receptor
Determines the set point for the variable and receives input from the receptor
Control Center
Adjust the value of the variable back to the set point
Effector
Returns the state of the body to homeostasis
Negative Feedback
Takes place when the deviation from set point becomes greater
Positive feedback
Standing upright, facing forward, upper limbs hanging to the side and palm facing forward
Anatomical Position
Separates the body into right and left halves
“The flight of an arrow”
Sagittal plane
A sagittal plane that passes through the midline of the body
Median plane
Dividing the body into superior and inferior portions
Transverse (horizontal) plane
Divides the body into anterior and posterior halves
Frontal plane
Cut made diagonally across the long axis
Oblique section
Two types of body cavities
Ventral body cavity
Dorsal body cavity
Encloses the organs of the nervous system
Dorsal body cavity
Cavity that houses the brain
Cranial cavity
Cavity that houses the spinal cord
Vertebral canal
Both brain and spinal cord are covered by membranes called
Meninges
Houses the vast majority of our internal organs collectively referred as VISCERA
Ventral body cavity
Houses primarily the heart and lungs
Thoracic cavity
Each closes a lung
Two lateral pleural cavities
Encloses heart and its major blood vessels
Medial mediastinum
Enclosed by abdominal muscles and consists of the more superior ABDOMINAL CAVITY and the more inferior PELVIC CAVITY
Abdominopelvic cavity
The organs of the abdominopelvic cavity are housed within the _____
Peritoneal Cavity
The walls of the body cavities and the surface of internal organs are in contact with membrane
Serous membrane
Layer that lines the walls of the cavities
Parietal serous membrane
The layer covering the internal organs
Visceral serous membrance
Containing the heart, is housed in the mediastinum
Pericardial cavity
Parietal serous membrane of the pericardial cavity
Parietal pericardium
Visceral serous membrane of the pericardial cavity
Visceral pericardium
Space between the two pericardial membranes the is filled with pericardial fluid
Pericardial Cavity
Cavity that houses each lung that is also the space between the pleural membranes
Pleural cavity
Parietal serous membrane lining the pleural cavities
Parietal pleura
Visceral serous membrane covering the lungs
Visceral pleura
Cavity that houses many internal organs
Peritoneal cavity
Parietal serous membrane in the peritoneal cavity
Parietal peritoneum
Visceral serous membrane in the peritoneal cavity
Visceral peritoneum
The regions of double-folded visceral peritoneum
Mesenteries
Inflammation of pericardium
Pericarditis
Inflammation of the pleura
Pleurisy
Inflammation of the peritoneum
Peritonitis
It is the basic living unit of all organisms
Cell
Specialized structures that perform specific functions
Organelles
Is an organelle containing the cell’s genetic material
Nucleus
The living material surrounding the nucleus is called
Cytoplasm
The cytoplasm is enclosed by the
Cell membrane or plasma membrane
Outermost part of the cell
Cell membrane
Materials outside the cell
Extracellular substances
Materials inside the cell
Intracellular substances
Containing the ends of the phospholipids are hydrophilic(water loving)
Polar
Fatty acids ends of the phospholipids are hydrophobic(water fearing)
Non-polar
Are involved with the movement of substances through the cell membrane
Membrane channels and carrier molecules
Are part of an itracellular communication system that enables cell recognition and coordination of the cell activities
Receptor molecules
Cell membranes are selectively permeable which means that they allow some substances
mema lang
Movement that does not require the cell to expand energy
Passive membrane transport
Movement that does require the cell to expand energy, usually in the form of ATP
Active membrane transport
Results from the natural, constant random motion of all solutes in a solution; tends to move from an area of lower concentration of a solute to an area of higher concentration
Diffusion (Passive membrane transport)
The difference in the concentration of a substance between two areas
Concentration Gradient
The phospholipid bilayer acts as a barrier to most water-soluble substances
Cell membrane channels
Constantly allow ions to pass through
Leak channels
Limit the movement of ions across the membrane by opening and closing
Gated Channels
The diffusion of water across a selectively permeable membrane such as the cell membrane
Osmosis
The force required to prevent the movement of water across a selectively permeable membrane
Osmotic pressure
other word for rupture in cell (swell)
Lysis or Hypotonic
Other word for cell’s shrinkage
Crenation or Hypertonic
Has a lower concentration of solutes and a higher concentration of water relative to the cytoplasm of the cell
Hypotonic solution
Has a higher concentration of solutes and lower concentration of water
Hypertonic solution
Refers to the state when two solutions have equal concentration of solutes across a semipermeable membrane
Isotonic solution
A carrier-mediated transport process that moves substances across the cell membrane from an area of higher concentration of that substance
Facilitated diffusion
A carrier-mediated transport process that moves substances across the cell membrane from regions of lower concentration to those of higher concentration against a concentration gradient
