Nervous System

Question 1

Gyri

Answer 1

folds on the surface of the cerebrum

Question 2

Sulci

Answer 2

grooves between the folds of the cerebrum

Question 3

Fissures

Answer 3

deep grooves between the folds of the cerebrum

Question 4

Diencephalon

Answer 4

area between the cerebrum and brainstem

Question 5

Cerebellum

Answer 5

portion of the brain in the posterior inferior region that processes information for coordination and movement

Question 6

Proprioception

Answer 6

position of joints

Question 7

Wernicke’s Area

Answer 7

specialized area in the brain that helps with understanding of speech

Question 8

Broca’s Area

Answer 8

specialized area in the brain that has to do with producing meaningful speech

Question 9

Nerves

Answer 9

a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs

Question 10

Cell body

Answer 10

the cell body carries genetic information, maintains the neuron’s structure, and provides energy to drive activities

Question 11

Dendrites

Answer 11

Dendrites are fibrous roots that branch out from the cell body, receiving and processing signals from the axons of other neurons

Question 12

Myosin

Answer 12

thick filaments of fibrous protein that forms (together with actin) the contractile filaments of muscle cells and is also involved in motion in other types of cells

Question 13

Actin

Answer 13

thin filaments of protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cell

Question 14

Sarcomere

Answer 14

the sarcomere is the fundamental unit of contraction and is defined as the region between two Z-lines. Each sarcomere consists of a central A-band (thick filaments) and two halves of the I-band (thin filaments)

Question 15

Myofibrils

Answer 15

very fine contractile fibers, groups of which extend in parallel columns along the length of striated muscle fibers. The myofibrils are made up of thick and thin myofilaments, which help give the muscle its striped appearance

Question 16

Cardiac muscle

Answer 16

cardiac muscle, also called myocardium, is one of three major muscle types, found only in the heart. The rhythmic contraction of cardiac muscle is regulated by the sinoatrial node of the heart, which serves as the heart’s pacemaker

Question 17

where is the brainstem located?

Answer 17

brainstem lies between the cerebral cortex and the spinal cord

Question 18

where is the pons located?

Answer 18

pons is the middle section of the brainstem
