Flashcards in Chapter 13 Deck (29):
0

The fora men magnum of the skull the spinal meninges are continuous

Cranial meninges

1

A series of specialized membrane surrounding the spinal cord provided the necessary physical stability and shock absorption

Spinal meninges

2

The layer that forms the outermost covering of the spinal cord

Dura mater

3

A region that contains areolar tissue, blood vessels, and a protective padding of adipose tissue

Epidural space

4

Acts as a shock absorber and a diffusion medium for dissolved gasses, nutrients, chemical messengers, and waste products.

Cerebrospinal fluid (CFS)

5

Consists of a mesh work of elastic and collagen fibers that is firmly bound to the underlying neural tissue

Pia mater

6

Outermost layer' consists of a dense network of collagen fibers

Epineurium

7

The middle layer extend inward from the epineurium these connective partitions divide the nerve into a series of compartments that contains bundles of axons

Perineurium

8

The inner most layer extend from the perineurium and surround individuals axons

Endometrium

9

Typically proximal to the white ramus together they are know as the rami communication

Gray ramus

10

Postganglionic fibers that innervates smooth muscles,glands,and organs,in the thoracic cavity extend directly from the ganglion to their respective effectors organs

White ramus

11

Adjacent spinal nerves blend their fibers producing a series of compound nerve trucks, such a complex interwoven network of nerves

Nerve plexus

12

Functional groups of interconnected neurons

Neural pool

13

Results from the connections that form between neurons during development

Innate reflexes

14

More complex learned motor patterns

Acquired reflexes

15

Provides a mechanism for the involuntary control of the muscular system

Somatic reflexes

16

Autonomic reflexes, control the activities of the other system

Visceral reflexes

17

An enhancement of spinal reflexes

Reinforcement

18

A spinal reflex in infants consisting of a fanning of the toes in responses to stroking the sole of the foot

Basin ski sign

19

The injection of anesthetic into the epidural space to eliminate sensory and motor innervation via spinal nerves in the area of injection

Epidural block

20

Inflammation of the meninges involving either the spinal cord or the brain generally caused by bacterial or viral pathogens

Meningitis

21

Regional losses of sensory and motor function as a result of nerve trauma disease or compression

Nerve palsies

22

Paralysis involving a loss of motor control of the lower but not the upper limbs

Paraplegia

23

A spinal reflex resulting from the stimulation of strength receptors in the quadriceps muscles

Patellar reflex

24

A spinal reflex in adults consisting of a curling of the toes in response to stroking the side of the foot sole

Plantar reflex

25

Paralysis involving the loss of sensation and motor control of the upper and lower limbs

Quadriplegia

26

A contrition caused by the infection of neurons in dorsal root ganglia by the varicella-zoster the primary sign is a painful rash along the sensory distribution of the affected spinal nerve

Shingles

27

A procedure in which cerebrospinal fluid is removed from the subarachnoid space through a needle, generally inserted between the lumbar vertebrae

Spinal tap

28

A spinal tap performed between adjacent lumbar vertebrae inferior to the conus medullaris

Lumbar puncture
