PNB 2774 Final Exam and All Actual
Answers 2026 Updated.
Anatomy - Answer study of structure "how does it look"
Physiology - Answer Study of function "what does it do"
Gross Anatomy - Answer Study of structures that can be seen with the naked eye
Microscopic Anatomy - Answer structures too small to be seen with the naked eye
Cytology - Answer study of cells
Histology - Answer study of tissues
anatomical position - Answer standing upright, feet parallel to floor, head level and looking
foward, arm at side of body with palms facing foward and thumbs pointing away from body.
inferior/superior - Answer below, above
proximal/distal - Answer closer to torso/further from torso
anterior/posterior - Answer front and back
medial/lateral - Answer toward the midline/away from the midline
ventral/dorsal - Answer belly side/backside
coronal plane - Answer divides body into front and back
transverse plane - Answer divides the body into superior and inferior parts
midsagittal plane - Answer divides the body into equal right and left sides
, Homeostasis - Answer a state of maintaining consistent internal conditions. multiple
"response loops" provide input and result in stabilizing output
homeostatic control system - Answer mechanisms that monitor the internal environment and
correct as needed
cellular level (local control) - Answer isolated change in a few cells or a tissue. response acts
locally
whole organism level (reflex control) - Answer long distance signaling, typically involving
endocrine or neural responses
Integrator - Answer control center that responds
ex of set point - Answer fever: increase set point for core body temp
Insulin - Answer lowers blood glucose levels
Glucagen - Answer raises blood glucose levels
Feedback - Answer some part of the output of a system is returned to its input in order to
regular its further output
negative feedback - Answer -when the output of a system acts to oppose the input of the
system
-shuts off original input
- helps maintain homeostasis
-self terminating
examples of negative feedback - Answer body temperature, blood pressure, glucose
regulation
positive feedback - Answer - occurs when the output of a system acts to increase the input of
the system
- require outside factors to shut down the system
- not homeostatic - amplifies stimulus further from setpoint
