Explanation / Answer

Match the following=

A ) Duramater= 4) tough outer covering of brain and spinal cord

B)arachnoid matter= 6)middle layer of meninges

C)piamater=5) innermost layer of menings which is in contact with brain and spinal cord matter

D)subdural space=12) space between duramater and arachnoid mater

E)sub arcahnoid space=13)space between arachnoid matter and piamater

F)cauda equina=14) nerves extending downward from conus medullaris which is the lowemost part of spinal cord

G)conus medullarus=9) taperend end of spinal cord

H)cervical.enlargement=10) it give rise to nerves that serves the upper limb

I) lumbar enlargement= 11)it gives rise to nerves that serves our lower limbs

J)spinal nerves =3) carries both sensory and motor impulses

K)posterior nerve root=1) it carries sensory nerve root towards spinal.cord

L)anterior nerve root=2) it carries motor impulsed away from spinal cord.

M)gray matter= 8)grey matter includes.anterior posterior and lateral.horns consisting of neuronal cell bodies

N)white matter= 7) white matter is made up of myelinated axons and connects different parts of gray matter

O)central canal=15 ) it carries csf(cebro spinal.fluid)down the center of spinalcord
