Sheep Brain

Cerebellum

The "little brain" attached to the rear of the brainstem; its functions include processing sensory input and coordinating movement output and balance. "Broccoli like Structure

Cerebral aqueduct

a canal connecting the third and fourth ventricles

Cerebrum

large part of the brain that controls the senses and thinking

Corpus Callosum

large band of white neural fibers that connects to to brain hemispheres and carries messages between them; myelinated; involved in intelligence, consciousness, and self-awareness; does it reach full maturity until 20s

Fornix

White matter "floor" of the lateral ventricles; involved with brain's memory center

Gyrus

a ridged or raised portion of a convoluted brain surface

Hypothalamus

a neural structure lying below the thalamus; directs eating, drinking, body temperature; helps govern the endocrine system via the pituitary gland, and is linked to emotion

Longitudinal Fissure

divides the cerebrum into right and left cerebral hemispheres

Medulla

Base of the brain stem which is nearest the spinal cord (1st bump) which controls breathing, heart rate and blood pressure

Optic Chiasma

the crossing of the optic nerves from the two eyes at the base of the brain (X like structure)

Optic Tract

the fibers from the optic chiasm to the LGN; posterior to the optic nerve

Pineal Gland

A small cone-shaped gland located in the roof of the third ventricle of the brain. Its major endocrine product is melatonin. Its endocrine role in the body is controversial.

Pituitary Gland

Small, round gland at the base of the brain:most important hormone secreting gland

Pons

a band of nerve fibers linking the medulla oblongata and the cerebellum with the midbrain (2nd bump above spinal chord the 1st is the medulla)

Spinal Chord

the conduit between the brain and the PNS for incoming sensory data and outgoing movement commands to the muscles

Sulcus

shallow grooves in cerebrum (black)

Thalamus

large egg-shaped structures of gray matter that form the dorsal subdivision of the diencephalon

Transverse Fissure

separates cerebral hemispheres from cerebellum

Ventricles 1-4

...

Cranial Nerves

12 nerves which carry impulses to and from the brain

Arbor Vitae

treelike branching of the cerebellar white matter; "tree of life
