1

The bodily structure of an organism and its parts

anatomy

2

The study of normal function of bodily structures & parts

physiology

3

The study of physiological, mechanical and psychological mechanisms of movement

kinesiology

4

the study of hearing disorders, evaluation, & rehabilitation

Audiology

5

the study of how sound is used across languages to convey meaning

phonology

6

the study of mental processes & behavior

psychology

7

What are the 3 types of muscle cells?

1. skeletal 2. cardiac 3. smooth

8

Describe skeletal muscle

1. is striated & under voluntary control
2. generates voluntary muscle movements

9

Describe cardiac muscle

1. striated & contracts involuntarily
2. Found in the heart wall and contracts to propel blood through the heart chambers

10

Describe smooth muscle

1. no striated & contracts involuntarily
2. specialized for relatively slow, sustained contraction in the internal organs, blood vessels, eyes, and hair follicles

11

What is the complex information processing system that enables interaction with the environment for survival & reproduction?

Nervous system

12

Purpose of a neuron

information reception and transmission

13

Parts of a neuron

1. Cell body with nucleus
2. dendrites
3. axons

14

What is specialized for transmitting or propogating APs in order to communicate with other neurons contract muscle or cause glands to secrete

axons

15

What is involved in processes specialized for receiving signals from other neurons or environmental stimuli?

dendrites

16

The brain and the spinal cord make up the...

CNS

17

What is the PNS comprised of?

Spinal & cranial nerves

18

How can the PNS be subdivided?

somatic NS & autonomic NS

19

What is the function of the somatic NS?

supports sensation & motor functions of the body

20

What is the function of the autonomic NS?

regulates digestion, heart rate, blood pressure, digestion, respiration, & gland secretion

21

What are the two branches of the autonomic NS?

1. Parasympathetic division
2. Sympathetic division

22

Purpose of the parasympathetic division of the ANS?

helps maintain homeostasis by balancing functions such as respiration, digestion, & various metabolic needs

23

Purpose of the sympathetic division of the ANS?

fight or flight response- increases heart rate, blood pressure, sweat production, respiratory rate

24

How does the CNS communicate with the body?

via peripheral nerves (spinal & cranial)

25

How many pairs of cranial nerves are in the PNS?

12

26

How many pairs of spinal nerves are in the PNS?

31

27

Which cranial nerve contributes to the oral stage of swallowing: chewing, bolus sensation?

CN V- trigeminal

28

Which cranial nerve is responsible for hearing & sound localization?

CN 8- Vestibulocochlear

29

What cranial nerve is responsible for bolus manipulation and propulsion during the oral stage?

CN XII- Hypoglossal

30

Which CN is responsible for head turning and should elevation?

CN XI- Spinal accessory
