Anatomy Study Brain And Spinal Cord

Front 1

Where does the spinal cord exit the cranium through?

Back 1

Foramen magnum

Front 2

The brain and spinal cord contain... (matter)

Back 2

Grey and white matter

Front 3

White matter is composed of

Back 3

Myelinated axons

Front 4

Gray matter is composed of

Back 4

unmyelinated axons, cell bodies and glial cells

Front 5

What are the 3 basic functions of the spinal cord?

Back 5

To conduct impulses to and fro
To coordinate spinal reflexes
Control certain repetitive functions

Front 6

Where is the spinal cord found?

Back 6

Vertebral canal

Front 7

The spinal cord is encircled by three connective tissue coverings collectively called the....

Back 7

Meninges

Front 8

The three meninges are:

Back 8

Dura Mater
Arachnoid Mater
Pia Mater

Front 9

This meninges is called the tough mother, and is the strongest of the 3 coverings

Back 9

The Dura Mater

Front 10

This meninges is surrounded by epidural space (between it and vertebrae) and is filled with fat

Back 10

Dura Mater

Front 11

This space is filled with mostly fat and acts to cushion the spinal cord

Back 11

Epidural Space

Front 12

This space is found between the dura mater and the arachnoid mater

Back 12

Subdural Space

Front 13

This thin, spider-web like layer is attached to the underside of the dura and is composed of collagen and elastic fibers

Back 13

Arachnoid Mater

Front 14

This space is found between the Arachnoid mater and the Pia mater

Back 14

Subarachnoid Space

Front 15

True or False: The subarachnoid space is filled with cerebrospinal fluid (CSF)

Back 15

True

Front 16

This meninges, also known as the delicate mother, is very thin and is in direct contact with the spinal cord. It contains many blood vessels

Back 16

Pia Mater

Front 17

These attach to the dura mater and help to hold the spinal cord in place within the vertebral canal

Back 17

Denticular ligaments

Front 18

The DENTICULATE LIGAMENTS are formed in the

Back 18

Pia Mater

Front 19

The end of the spinal cord is called the

Back 19

Medullary cone

Front 20

This extension of the Pia Mater connects the medullary cone to the tip of the coccyx

Back 20

Terminal Filum

Front 21

The collection of nerves below L2 within the vertebral canal is called the:

Back 21

Cauda Equine

Front 22

Spinal nerves exit the vertebral canal through the:

Back 22

Intervertebral foramen

Front 23

This enlargement in the spinal cord supplies nerves to the arm

Back 23

Cervical Enlargement

Front 24

This enlargement in the spinal cord supplies nerves to the leg

Back 24

Lumbosacral enlargement

Front 25

Sensory neurons enter through this opening in the spinal cord

Back 25

Dorsal Horn

Front 26

Bundles of axons in the CNS are called

Back 26

Tracts

Front 27

Networks formed by tracts leaving the spinal cord are called

Back 27

Plexus

Front 28

Bundle of nerve cell bodies in the PNS are called

Back 28

Ganglion

Front 29

Groups of nerve cell bodies in the CNS are called

Back 29

Nucleus/Nuclei

Front 30

The Epineurium surrounds:

Back 30

Entire Nerve

Front 31

The Spinal Cord is divided into two parts by the:

Back 31

Anterior median fissure & Posterior median sulcus

Front 32

The Perineurium surrounds

Back 32

Bundles of axons within a nerve

Front 33

The Endoneurium surrounds

Back 33

An individual axon and its myelin sheath

Front 34

Sensory nerves leave the spinal cord through this opening

Back 34

The ventral horns

Front 35

Bundles of axons in the PNS are called

Back 35

Nerves

Front 36

Bundles of axons in the PNS are called _____, while bundles of axons in the CNS are called _____

Back 36

Nerves,

Tracts

Front 37

Groups of nerve cell bodies in the PNS are called ______, while groups of nerve cell bodies in the CNS are called _______/

Back 37
