100% Correct | Verified 2024
How are anatomy and physiology related? - ✔✔Anatomy is the study of the internal and external parts
of the body.
Physiology is how living organisms perform their vital functions.
List and describe the specialties of anatomy. - ✔✔
Systematic anatomy: groups of organs working together (skeletal system)
-Developmental anatomy:from egg to maturity
-clinical anatomy: medical specialties(surgical anatomy)
Microscopic anatomy examines cells and molecules:
-cytology: cells and their structures
-histology: tissues and their structures
List and describe the specialties of physiology - ✔✔-Cell physiology: processes within and between cells
-Organ physiology: functions of specific
-Systemic physiology: functions of an organ system
-Pathological physiology: effects of diseases
Name the levels of structural organization that make up the human body and explain how they're
related. - ✔✔Chemical-cellular-tissue-organ-system-organism.
Define metabolism. - ✔✔the chemical reactions occurring in the cells and tissues of the body
,Compare and contrast catabolism with anabolism. Use examples to help understand the differences. -
✔✔Catabolism: tearing down; decomposition of complex molecules within the body's cells or
tissues(breaking down glucose)
Anabolism: building up; synthesis of new molecules within the body's cells or tissues
Define homeostasis and explain its importance - ✔✔is the property of a system in which variables are
regulated so that internal conditions remain stable and relatively constant.
Compare and contrast intrinsic and extrinsic regulation. Use examples to help understand the difference
- ✔✔Intrinsic regulation: autoregulation
-levels decrease at a tissue
Extrinsic regulation: more distant regulation
-during exercise
List and describe the three control systems involved in maintaining homeostasis - ✔✔Receptor (sensor)
-respond to changes in the environment
-sends info to control center
Control Center (intergrator)
-determines set point
-analyzes info
-determines appropriate response
Effector
-provides a means for response to the stimulus
Compare and contrast negative and positive feedback. Use examples to help explain each. - ✔✔Negative
feedback:
-includes homeostatic control mechanisms
-shuts off the original stimulus, or reduces its intensity once balance in the body is reached
, Positive feedback:
-increases the original stimulus to push the variable farther
-in the body this only occurs in blood clotting and birth of a baby
Describe a person in anatomical position - ✔✔hands at sides
palms facing forward
feet together
on back
Define Anterior - ✔✔the front side
Define posterior - ✔✔the back side
Define lateral - ✔✔farther away from body
Define medial - ✔✔close to body
Define proximal - ✔✔closer to body-in terms of arm would be shoulder
Define distal - ✔✔farther from body-in terms of arm would be fingers
Define superficial - ✔✔toward or at the body surface
Define deep - ✔✔away from the body surface
Define intermediate - ✔✔In between
