SOLUTION TESTED QUESTIONS 2026
COMPLETE STUDY GUIDE VERIFIED
CONTENT
⩥ physiology. Answer: understanding how something functions with
respect to its anatomy
*study of the function
⩥ what is the importance of studying comparative Anatomy and
Physiology?. Answer: studying similarities between animals helps
understand form and functions of homologous structures ( come from
same origin)
⩥ Neurophysiology
Endocrinology
Pathophysiology. Answer: -study of the nervous system
- study of endocrine system
- study of diseases and disorders
⩥ human implications and why do we study evolution?. Answer: closest
relative? chimp
genetic difference? 1.6%
,helps choose animals for research
medical derivates
⩥ Human shared adaptations. Answer: 1. opposable thumbs (grab onto
things)
2. Bipedalism (walk up right on 2 legs)
3. endurance (ability to run long distance)
4. brain size and folding (increases surface ares)
⩥ Hierarchy of Complexity (least to greatest complexity). Answer:
atom, molecule, organelle, cell, tissue, organ, organ system, organism
⩥ Anatomical variation and its importance in clinical research. Answer:
no two humans are exactly alike, this means the medical field has to
watch dosage and not all procedures and histology slides will be
identical
⩥ homeostasis. Answer: maintaining stability in a dynamic environment
⩥ negative feedback mechanism (most common). Answer: helps keep
variables close to set point and bringing things back to normal
ex: body heat (like house thermostat)
nerve cells in brain monitor temp.
, ⩥ positive feedback mechanism. Answer: mechanism that amplifies
change in the same direction
rapid change
ex: childbirth
⩥ 3 components of feedback mechanism loop. Answer: receptor- detects
a change and send message to integration center
integration center- tells something to do something
effector-causes the change
⩥ gradients and flow. Answer: central concept of living systems
difference in:
- chemical concentration
- electric charge
- pressure
- temp.
⩥ anatomical positions. Answer: anterior
posterior
midline
lateral
