Solutions Latest Update
Explain the principle of complementarity. - ANSWER -Anatomy and physiology
are inseparable because function always reflects structure examples.) bones
support and protect body organs because they contain hard mineral deposits and,
blood flows in one direction through the heart because the heart has valves that
prevent back flow.
Negative and Positive Feedback Mechanisms - ANSWER -Negative Feedback
Mechanisms- In these systems, the output shuts off the original stimulus or reduces
intensity. Examples: Regulation of body temperatures; Withdrawal Reflex in
which the hand is jerked away from a painful stimulus such as a broken glass; As
blood volume drops, the hypothalamus of the brain is stimulated to release ADH to
the blood.
Positive Feedback Mechanisms- The result or response enhances the original
stimulus so that the activity is accelerated. Examples: Homeostatic mechanisms are
the enhancement of labor contractions during birth and blood clotting.
Homeostatic Imbalance and Disease. - ANSWER -Most disease can be regarded
as a result of the disturbance of homeostasis, which is known as homeostatic
imbalance. Any abnormal condition is known as homeostatic imbalance.
9 Regions of Abdominopelvic Regions - ANSWER -1) Right Hypchondriac
Region (Top right) Organ: Liver Gallbladder
2) Right Lumbar Region (Middle Right) Organs: Ascending Colon of large
intestine
3) Right Iliac (inguinal) region- Cecum
4) Epigastric Region (middle top) Organs: Stomach
5) Umbilical Region (middle middle) Organs: Small intestine and Transverse colon
of large intestine.
, 6) Hypogastric (pubic) region (Bottom middle) Organs: Urinary Bladder
7) Left Hypochondriac Region (Top left) Organs: Diaphragm
8) Left Lumbar Region (Middle Left) Organs: Descending colon of large intestine.
9) Left Illiac (inguinal) region (Bottom Left) Organ: Initial part of sigmoid colon
Four Abdominopelvic Quadrants - ANSWER -1) Right upper Quadrant
2) Left upper quadrant
3) Right lower Quadrant
4) Left lower quadrant
Structure of the Generalized Cell - ANSWER -Cell membrane, cytoplasm,
nucleus, endoplasmic reticulum, ribosome, golgi body, mitochondrion, lysosome.
For picture refer to page 66.
Epithelial Tissue (Simple squamous) - ANSWER -Description: Single layer of
flattened cells with disc-shaped central nuclei and sparse cytoplasm. Simplest of
the epithelia.
Function: Allows passage of materials by diffusion and filtration. Secretes
lubricating substances in serosae
-Forms walls of air sacs of the lungs and lines blood vessels
-It contributes to
Nervous Tissue Characteristics - ANSWER -Description: Neurons are branching
cells cell processes that might be quite long extend from the nucleus-containing
cell body. Also contributing to nervous tissue are non irritable supporting cells.
Function: Transmit electrical signals from sensory receptors and to effectors
(muscles and glands) which control their activity.
Location: Brain, spinal cord, and nerves
Skeletal Muscle Tissue - ANSWER -Description: long, cylindrical, multinucleate
cells; obvious striations
Function: voluntary movement; locomotion, manipulate of the environment; facial
expression; voluntary control
Location: in skeletal muscles, attached to bones or occasionally to the skin
