Flashcards in 3rd Test Deck (32):
1

What neurotransmitter would take longer to take effect once it arrived at the post-synaptic neuron

Substance P

2

Ambidexterity leads to

Dyslexia

3

To cause an action potential, neurotransmitters released in several waves unto the next neuron

Temporal summation

4

definition of "consciousness"

awareness of one's self

5

brain waves produced when under anesthesia

Delta waves

6

Which part of the neuron produces neurotransmitters

the cell body

7

Origin for the flexor carpi ulnaris is most likely found on the

Ulna

8

Efferent neurons are also known as

Motor Neurons

9

The muscle "pectoralis minor" is named this because

of the relative size it has to another muscle

10

Aspartate could affect memory by

causing depolarizations in the CNS

11

Parts of the blood-brain barrier

Thick basal lamina and astrocytes

12

What is a short protein used as a neurotransmitter

Enkephalin

13

Process of action potential occuring

Action potential arrives at cell body, it travels past axon hillock and goes down axon collateral, calcium channels open allowing calcium to enter cell, synaptic vessels fuse to membrane of cell, and neurotransmitter is released

14

Which parts of the brain is involved in emotions

Limbic system and Hypothalamus

15

Neurons classified as unipolar

neurons in the dorsal root ganglion

16

Using the"staircase effect"

swinging a golf club a few times prior to teeing off

17

slow twitch muscle

the leg of a cow

18

the cerebral cortex is made mainly of

gray matter

19

Which of the following supporting cells produce myelin sheaths in the peripheral nervous system

Schwann Cells

20

The ability for a muscle to stretch beyond its normal length is

extensibility

21

The functional unit of a skeletal muscle is

sarcomere

22

Frontal lobotomies led to

the inability to make decisions and verbalize one's thoughts

23

Drainage areas for cerebrospinal fluid in the brain are called

dural sinuses

24

what would not be a reason to routinely exercise

to reduce the excess lactic acid building up in the muscles

25

what is the charge of a cell membrane following hyperpolarization if it had been inactive

-90mV

26

When flexing the elbow, the antagonist to this movement would be the

triceps brachii

27

What would contain a multiunit smooth muscle

irises of the eyes

28

If a tumor causes constant lose of balance, what part of the brain is it on

cerebellum

29

Which stage of sleep would a person have dreams

REM sleep

30

for a cordotomy, a surgeon must carefully cut which of the following to relieve pain that doesn't seem to go away

an ascending tract of the spinal cord

31

Electrical synapses would be found

only in the CNS

32

What situation is most likely to be handled almost entirely by the cerebrum

Deciding to hold your breath
