brain

Answer 0

brain

Question 1

central nervous system (CNS)

Answer 1

brain & spinal cord

Question 2

cerebrum

Answer 2

largest portion of the brain

Question 3

frontal lobe

Answer 3

part of the cerebrum responsible for muscle movement and personality

Question 4

parietal lobe

Answer 4

part of the cerebrum responsible for pain, temperature and touch

Question 5

temporal lobe

Answer 5

part of the cerebrum responsible for hearing, taste and smell

Question 6

occipital lobe

Answer 6

part of the cerebrum responsible for vision

Question 7

cerebral cortex

Answer 7

part of the cerebrum responsible for higher mental function; gray matter

Question 8

thalamus, diencephalon

Answer 8

2 gray matter nuclei deep in the brain responsible for relaying sensory info to the cortex

Question 9

gyri

Answer 9

mounds of the cerebral hemispheres

Question 10

sulci

Answer 10

shallow grooves that separate gyri

Question 11

fissures

Answer 11

deep grooves in the brain

Question 12

cerebellum

Answer 12

portion of the brain located below the occipital lobe of the cerebrum; responsible for coordination and control of skeletal muscles

Question 13

brainstem

Answer 13

region of the brain that serves as a relay between the cerebrum, cerebellum and spinal cord; responsible for autonomic functions; 3 levels - mesencephalon; pons and medulla oblongata

Question 14

ventricles

Answer 14

interconnected cavities within the brain filled with cerebrospinal fluid

Question 15

cerebrospinal fluid (CSF)

Answer 15

plasma-like clear fluid circulating in and around the brain and spinal cord

Question 16

spinal cord

Answer 16

column of nervous tissue from the brainstem through the vertebrae; responsible for nerve conduction to and from the brain and body

Question 17

meninges

Answer 17

3 membranes that cover the brain and spinal cord - the dura mater, pia mater and arachnoid mater

Question 18

peripheral nervous system (PNS)

Answer 18

nerves that branch from the CNS, including cranial nerves and spinal nerves

Question 19

cranial nerves

Answer 19

12 pairs of nerves arising from the brain

Question 20

spinal nerves

Answer 20

31 pairs of nerves arising from the spinal cord

Question 21

sensory nerves

Answer 21

nerves that conduct impulses from the body to the brain; aka afferent nerves (ad = toward; ferre = carry)

Question 22

motor nerves

Answer 22

nerves that conduct motor impulses from the brain to the body; aka efferent nerves (e = out; ferre = carry)

Question 23

autonomic nervous system (ANS)

Answer 23

nerves that carry involuntary impulses to smooth muscle, cardiac muscle, and various glands

Question 24

hypothalamus

Answer 24

control center for the ANS located below the thalamus (diencephalon)

Question 25

sympathetic nervous system

Answer 25

division of the ANS that preps the body for a fight or flight response

Question 26

parasympathetic nervous system

Answer 26

division of the ANS that counterbalances the sympathetic nervous system by returning the body to a restful state
