Question 1

Afferent

Answer 1

Nerves that are conducting information to a location

Question 2

Anterior

Answer 2

Nearer the front

Question 3

Arachnoid Membrane

Answer 3

A fine, delicate membrane, the middle one of the three membranes or meninges that surround the brain and spinal cord, situated between the dura mater and the pia mater.

Question 4

Brain

Answer 4

An organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating centre of sensation and intellectual and nervous activity.

Question 5

Brain stem

Answer 5

The central trunk of the mammalian brain, consisting of the medulla oblongata, pons, and midbrain, and continuing downwards to form the spinal cord.

Question 6

Caudal

Answer 6

At or near the tail or the posterior part of the body

Cerebellum

Answer 8

The part of the brain at the back of the skull in vertebrates, which coordinates and regulates muscular activity.

Question 9

Cerebrospinal Fluid

Answer 9

Clear watery fluid which fills the brains ventricles and the space between the arachnoid membrane and the pia mater.

Question 10

Cerebrum

Answer 10

The principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, left and right, separated by a fissure.

Question 11

Choroid Plexus

Answer 11

A network of blood vessels in each ventricle of the brain, producing the cerebrospinal fluid

Question 12

Contralateral

Answer 12

Relating to or denoting the side of the body opposite to that on which a particular structure or condition occurs.

Question 13

Coronal

Answer 13

Relating to the crown of the head
