A

occipital lobe

21
Q

controls the sense of smell and hearing; has a role in memory

A

temporal lobe

22
Q

the largest part of the brain; controls your ability to read, write, and speak; also related to your mathematical and musical skills; also deals with your memory

A

cerebrum

23
Q

helps in the smooth coordination of skeletal muscle contractions; also
regulates body posture and balance

A

cerebellum

24
Q

connects the brain and the spinal cord; consists of three regions

A

brain stem

25
Q

associated with heartbeat, breathing, sensations, and reflex control when a person is swallowing, vomiting, coughing, hiccupping, and sneezing.

A

medulla oblongata

26
Q

has several functions that include
the coordination of muscular movements and
reflexes that direct the movement of the eyes,
head, and neck every time we need to look at
things around us; also responsible for your startle
reflex, which happens whenever you are surprised
due to loud or noisy sounds

A

midbrain

27
Q

connects the parts of the brain; also helps
control breathing

A

pons

28
Q

also called the neuron, has the ability change a stimulus into an impulse

A

nerve cell

29
Q

an electric signal that travels in it.

A

impulse

30
Q

is a change in the environment that causes one to initiate an impulse

A

stimulus

31
Q

The neuron has three parts, namely,

A

the cell body, the dendrites, and the axon.

32
Q

contains the nucleus and other cell organelles.

A

cell body

33
Q

are the receiving parts of the neuron.

A

dendrites

34
Q

transmits impulses to another neuron.

A

axon

35
Q

also known as the afferent neurons; receive stimuli and transmit them toward the CNS

A

sensory neurons

36
Q

known as the efferent neurons; carry the impulse away from the CNS to the effectors such as the muscles and the glands

A

motor neurons

37
Q

also called association neurons; responsible for processing the sensory information carried by the sensory neurons and giving a response through the motor neurons

A

Relay neurons or Interneurons

38
Q

connect
the nervous tissues together
