Q

is involved in primary auditory perception, such as hearing, and holds the primary auditory cortex

A

TEMPORAL LOBE

19
Q

receives sensory information from the ears and secondary areas process the information into meaningful units such as speed and words

A

TEMPORAL LOBE

20
Q

are soft and delicate, even slight pressure can injure the irreplaceable neurons

A

NERVOUS TISSUE

21
Q

what encloses the brain and spinal cord?

A

SKULL AND VERTEBRAL COLUMN

22
Q

what are the 3 additional protection for the Central nervous system

A
  1. MENINGES
  2. CEREBROSPINAL FLUID
  3. BLOOD-BRAIN BARRIER
23
Q

Other term for cerebrum

A

CEREBRAL HEMISPHERES

24
Q

refers to the membranous covering of the brain and spinal cord

A

MENINGES

25
Q

Outermost layer of the meninges

A

DURA MATER

26
Q

middle, meningeal layer of the meninges

A

ARACHNOID MATER

27
Q

innermost layer, clings tightly to the surface of the brain

A

PIA MATER

28
Q

It is a watery “broth” with the components similar to blood plasma

A

CEREBROSPINAL FLUID (CSF)

29
Q

It is a clear, colorless body fluid found in the brain and spinal cord

A

CEREBROSPINAL FLUID (CSF)

30
Q

it is to protect the CSN against circulating toxins or pathogens that could cause brain infections, while at the same time allowing vital nutrients to reach the brain.

A

BLOOD-BRAIN BARRIER

31
Q

it is a long, thin, tubular structure made up of nervous tissues, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column

A

SPINAL CORD

32
Q

functions primarily in the transmission of nerve signals from the motor cortex of the body, and from the afferent fibers of the sensory neurons to the sensory cortex

A

SPINAL CORD

33
Q

it is also a center for coordinating many reflexes and contains reflex arcs that can independently control reflexes.

A

SPINAL CORDS

34
Q

refers to the parts of the nervous system outside the brain and spinal cord

A

PERIPHERAL NERVOUS SYSTEM

35
Q

What includes in the peripheral nervous system (4)

A
  1. Cranial nerves
  2. Spinal nerves and their roots and branches
  3. Peripheral Nerves
  4. Neuromuscular junctions
36
Q

is an enclosed, cable-like bundle of axons (the projections of neurons) in the peripheral nervous system

A

NERVE

37
Q

provide structured pathways that support the electrochemical nerve impluses transmitted along each of the axons.

A

NERVE

38
Q

what is nerve cells called?

A

NEURON

39
Q

5 parts of the neuron

A
  1. SOMA OR CELL BODY
  2. DENDRITES
  3. AXON
  4. MYELIN SHEATH
  5. SCHWANN CELL
40
Q

supports the chemical processing of the neuron, the most important of which is the production of neurotransmitters

A

SOMA OR CELL BODY

41
Q

are appendages that are designed to receive communications from other cells

A

DENDRITE

42
Q

A long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma

A

AXON

43
Q

an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord

A

MYELIN SHEATH

44
Q

play an essential role in the survival and functions of neurons

A

SCHWANN CELL
