Interprets sensory input and initiates voluntary muscular responses. (Kaindl, 2020)

Question 2

Thalamus

Answer 2

Directs impulses to different parts of the brain. (Kaindl, 2020)

Question 3

Corpus Callosum

Answer 3

Transmittes motor, sensory, and cognitive information between the left and right hemispheres of the brain.
(Corpus Callosum, 2020)

Question 4

Hypothalamus

Answer 4

Controls the pituitary gland and nerve signals to maintain homeostasis. (Kaindl, 2020)

Question 5

Pons

Answer 5

Connects the left and right neurons in the cerebrum, cerebellum, and the rest of the brain.

Question 6

Cerebellum

Answer 6

Controls conscious and unconscious motor movements and coordination.

Question 7

Spinal Cord

Answer 7

Connects the peripheral nervous system to the brain.

31 pairs of nerves

Question 8

Pituitary Gland

Answer 8

Controls hormones and sends messages to other glands to create hormones.

Question 9

Medulla Oblongata

Answer 9

Controls involuntary responses such as breathing and heart rate. (Kaindl, 2020)

Question 10

Meninges (Dura Mater)

Answer 10

Prevents blood and toxins from flowing into the central nervous systems cells. (Kaindl, 2020)

Question 11

Midbrain

Answer 11

Relays sight and sound information between the hindbrain and forebrain. (Kaindl, 2020)

Question 12

Ventricles

Answer 12

Cavity that produces and stores cerebral spinal fluid which nourishes the cells of the central nervous system and cushions the brain. (Kaindl, 2020)

Question 13

Brainstem

Answer 13

Regulates involuntary actions such as breathing and heart rate.
(Lorenzo Crumbie, 2020)

Question 14

Occipital Lobe

Answer 14

Responsible for visual recognition and vision. (Kaindl, 2020)

Question 15

Frontal Lobe

Answer 15

Controls memory, intelligence, conscious thought, emotions, voluntary muscle movement, and personality. Contains the Broca’s Area which controls the motor area for speech. (Kaindl, 2020)

Question 16

Temporal Lobe

Answer 16

Processes auditory information from the ears. Contains Wernick’s Area which controls comprehending and understanding speech. (Kaindl, 2020)

Question 17

Parietal Lobe

Answer 17

Processes information about the body’s position and receives sensory information from the skin. (Kaindl, 2020)

Question 18

Dendrites

Answer 18

carries impulses towards the cell body

Question 19

Cell Body

Answer 19

recieves input from dendrites and relays it to the axons

cite of cells metabolism

Question 20

Axons

Answer 20

carry impulses away from the cell body

Question 21

Myelin Sheath

Answer 21

speeds nerve impulse transmissions, helps protects the neutrons, and prevents the loss of Na+ and K+ ions from the nerve cell

Question 22

Node of Ranvier

Answer 22

the impulse jumps from one node to the other

Question 23

Axon Terminals

Answer 23

communicate with other neutrons through releasing neurotransmitters to receptors of other neutrons

Question 24

Pathway of the nerve Impulse

Answer 24

sensory receptor
sensory neuron
interneuron
motor neuron
effector

Question 25

Sensory Neurons

Answer 25

carry impulses from the sensory receptor to the CNS

Question 26

Interneurons

Answer 26

process and integrate information from the sensory neuron

Question 27

Motor Neuron

Answer 27

carry information from the CNS to the effectors

Question 28

The synapse

Answer 28

connection btw two neutrons

Question 29

Synaptic Cleft

Answer 29

space btw the axon end of one neutron and the dendrite of another

Question 30

Pre synaptic cleft

Answer 30

the membrane the impulse travels to before the synapse | at the axon end

Question 31

Post synaptic cleft

Answer 31

the membrane the impulse is travelling to across the synapse at the other neutrons dendrite

Question 32

CNS

Answer 32

contains the brain and spinal cord | coordinates messages received from and sent to nerves

Question 33

PNS

Answer 33

Sensory pathway in th the CNS | motor pathway out of the CNS

Question 34

Glial cells

Answer 34

provide structural support for the nervous system tissue

Question 35

How neurons work

Answer 35

``` receptor sensory neuron interneuron motor neuron effector ```

Question 36

neurolemma

Answer 36

helps regenerate damaged axons in the PNS

Question 37

Reflex

Answer 37

rapid, predictable, involuntary response to stimuli

Question 38

reflex arc

Answer 38

neuron pathway for reflex actions | stimulus, sensory receptor, spinal cord/interneurons, effectors

Question 39

Somatic system

Answer 39

voluntary control (skeletal muscles)

Question 40

Automatic system

Answer 40

involuntary control (hypothalamus and medulla oblongata) detects and maintains homeostasis divided into two parts sympathetic ns and parasympathetic ns
