Bio 319 PROCTORED EXAM 2025! MOSTLY TESTED
QUESTIONS WITH CORRECT ANSWERS - ALREADY
GRADED A+
prefrontal cortex - (answers)ability to think faster, last thing to develop
what can we outwardly control? - (answers)skeletal muscle
Change the form - (answers)change the function
What is physiology - (answers)5 ions
Na, K, Ca, Cl, Mg
move down concentration gradient
4 tissue types - (answers)epithelial, connective, muscle, nervous (all have RMP)
AP vs RMP - (answers)AP = action potential
RMP = resting membrane potential
Homeostasis - (answers)a balance in the body's internal environment
Stimuli - (answers)what living things respond to
what increases surface area? - (answers)branches, flattens, folds
cytology - (answers)cellular anatomy
histology - (answers)study of tissue
,AP vs RMP - (answers)Only nervous and muscular have AP. All 4 have RMP
lithotripsy - (answers)sonic waves that break up stones
Visceral vs Parietal - (answers)The parietal layers of the membranes line the walls of the
body cavity. The visceral layer of the membrane covers the organs.
ultrasound - (answers)sound waves pass into body and bounce back to receiver (sonogram)
X-ray - (answers)electromagnetic radiation moves through body and is exposed on
photographic plate; creates radiograph
X-ray - (answers)denser is its, the wider it will appear
suture = joints that do not move
ie 2 cranial bones, 2 immovable bones
made -> looks like -> breaks down -> pharmacology perfect
CO2 and pH relationship - (answers)Inversely related
Blood pH up = CO2 down
- Consists of the lungs and respiratory passages
Angio - (answers)vessel
Types:
-Blood
-Lymphatic
ischemia - (answers)No oxygen to a region
Hypoglycemia - (answers)low blood sugar
, Brain and RBCs in trouble b/c it runs on glucosis
RBC's don't have mitochondria; go through glycolysis (break sugar) to make ATP
interstitium - (answers)space between cells containing interstitial fluid
- interstition: gap between cells
Apoptosis - (answers)programmed cell death
- apoptosis of limb buds to digits so you don't have webbed hands
effects of aging on tissues - (answers)1. Cells divide more SLOWLY (irony of cancers in elders)
2. Rate of blood cell synthesis goes DOWN
3. Collagen fibers become more IRREGULAR; increase in number; tendons/ ligaments
become less flexible and more fragile
4. Elastic fibers become LESS elastic
5. Changes in collagen and elastin =
- Arterial walls/elastic ligaments become less elastic
- atherosclerosis and reduced blood supply to tissues
- Wrinkling of skin (hyaluronic acid)
-Increased tendency for bones to break
synovial membrane - (answers)- lines freely moveable joints
- very slippery
- produce fluid rich in hyaluronic acid to help to maintain high fluid viscosity and normal
integrity of the joint by reducing inflammation and preserving the normal cartilaginous
matrix.
TMJ - (answers)Type of joint: hinge, ball and socket, synovial
- jaw moves OUT of socket during normal function
- Lee's x-ray
