Anatomy and Physiology Compared
The study of the structure of the body parts and their relationships to on another
ANATOMY
The defintion "Atoms combined to form molecules" is known as?
CHEMICAL
Animals on two feet (bipedal) posterior is their BACK and anterior is the BELLY
Define Variable and Stress
Things that have am effect on homeostasis is VARIABLE
Disruption of homeostasis is STRESS
INTRACELLULAR FLUID?
EXTRACELLULAR FLUID?
INTERSITIAL FLUID?
INTRACELLULAR is INSIDE the cell EXTRACELLULAR is OUTSIDE the cell INTERSITIAL FLUID is BETWEEN cells
The study of functions of the body's structural machinery
PHYSIOLOGY
The definition "cells are made of molecules" is known as?
CELLULAR
Inferior/Superior
Superficial/Deep
Medial/Lateral
Proximal/Distal
Inferior is closer to FEET; Superior is farther from feet
Superficial is closer to SKIN SURFACE; Deep is farther from skin surface
Medial is closer to inside of body; Lateral is closer to outside of body
Proximal is closer to trunk; Distal is farther from trunk
Describe the components of typical homeostatic mechanism
Variables produce a change in the body
THREE interdependent components are
Receptor: monitors the environments and responds to changes (stimuli)
Control center: determines the set point at which the variable is maintained
Effector: provides the means to respond to stimuli
What is DIFFUSION and how do molecules diffuse across plasma membrane?
DIFFUSION is movement of particle from an area of higher concentration to low concentration
Molecules diffuse across plasma membrane by concentration of gradient
Regional, Systemic and Surface all relate to what?
GROSS ANATOMY
Difference between tissue and organ
TISSUE consists of SIMILAR CELLS
ORGAN is made up of DIFFERENT TISSUES
Describe the plasma membrane in terms of fluid mosaic model
Plasma membrane is composed two layers of lipid molecules with protein molecules dispersed within
Compare general aspects of positive feedback systems with negative feedback systems
Positive ENHANCES original stimulus
Negative SHUTS off original stimulus
DEFINE and GIVE EXAMPLE of OSMOSIS
Movement of a solvent through a semipermeable membrane into a solution of higher solute concentrate.
EXAMPLE is WRINKILING OF FINGERS IN WATER
Difference between Cytology and Histology
Cytology is the STUDY OF CELLS
Histology is the STUDY OF TISSUES
Consist of different organs that work closely together
ORGAN SYSTEM
DESCRIBE the MAJOR body cavities and ORGANS found in each
SPINAL Cavity (house of brain and pituitary gland)
CRAINIAL Cavity (house of spinal cord)
THORACTIC Cavity (house of lungs)
ABDOMINAL Cavity (house of major digestive organs)
PELVIC Cavity (house of urinary and reproductive organs)
Define HOMEOSTASIS
Ability to maintain a relatively stable internal environment in an ever-changing outside world
What happens to cell in HYPERTONIC, HYPOTONIC, ISOTONIC SOLUTIONS
Hypertonic: water leaves cell and cell shrinks
Hypotonic: water enters cell and cell swells
Isotonic: no change to cell
Study of structural changes caused by disease
PATHOLOGY
Made up of the organ systems
ORGANISMAL
DIFFERENCE between transversal, frontal and sagittal cuts in the body
TRANSVERAL: superior and inferior components
FRONTAL: anterior and posterior (front/back)
SAGITTAL: left and right components (left/right)
Example of NEGATIVE and POSITIVE FEEDBACK
NEGATIVE: Getting cold, body neg. response is shivering
POSTIVE: Getting hot, body pos. response is sweating
What FIVE factors effect the rate of transport of substance across cell membrane
Explain EACH factor
1.MATERIAL 2.TEMPARATURE 3.PRESENCE OR ABSEMCE OF CHANNELS 4.PARTICLE CHARGES 5.CONCENTRATION OF GRADIENT FOR THE MATERIALS TRANSPORTED
EXPLAIN EACH (check notes)
