Pta 120 Quiz 2 Part 2

Front 1

What are the three layers of the meninges?

Back 1

1. Dura mater: thick, most fibrous, tough outer layer

2. Arachnoid: middle, thinner layer

3.Pia mater: inner, most delicate layer which carries blood vessels to the brain

Front 2

Where does cerebrospinal fluid belong?

Back 2

In the subarachnoid space (this is located between the layers of the arachnoid and pia mater. cerebrospinal fluid surrounds the brain and fills the ventricles within.

Front 3

What is the difference between gray matter and white matter?

Back 3

Gray matter has 3 functions transmitted by 3 parts: The posterior horn transmits sensory impulses.The anterior horn transmits motor impulses. The posterior columns transmits the sensations of proprioception, pressure, and vibration.

White matter contains ascending (sensory) and descending (motor) fiber pathways. Each pathway carries a specific type of impulse, such as touch, to and from a specific area.

XI. Spinal accessory: (motor) SCM and trap muscles, swallowing

XII. Hypoglossal: (motor) muscles of tongue

Front 7

Where do the first seven cervical nerves (C1-C7) exit the vertebral column?

(Pg 60 under spinal nerves paragraph)

Back 7

ABOVE the corresponding vertebrae. For example, the C3 nerve exits above the C3 vertebrae.

Front 8

Where does the C8 nerve exit?

Back 8

UNDER C7 and OVER T1, since there is one more cervical nerve than there are vertebrae.

Front 9

Where do the 12 thoracic nerves exit?

Back 9

UNDER the corresponding vertebrae.

Front 10

Where do the 5 lumbar nerves exit?

Back 10

UNDER the corresponding vertebrae.

Front 11

Front 12

True or False:

The coccygeal nerve exits below the coccyx.

Back 12

TRUE

Front 13

What are the names of the 3 plexuses?

Back 13

1. Cervical plexus

2. Brachial plexus

3. Lumbosacral plexus

Front 14

Where do the elbow flexors receive innervation?

Back 14

C5 and C6 nerves

pg. 63, second paragraph

Front 15

True or False:

A person with an injury at or above C3 would NOT ahve the function of the diaphragm and would be unable to breathe without assistance.

Back 15
