Anatomy and Physiology - Mrs.Ryles

fourth ventricle

The structure between the brain stem and the cerebellum

medulla oblongata

The region of the brain that connects the spinal cord to the brain

optic nerve

Nerve that carries visual information

Cerebrum

the most complex part of the brain, Conscious thought

Olfactory Nerve

Nerve composed of sensory fibers for the sense of smell and is located in the roof of the nasal cavity

Oculomotor Nerves

Nerve that innervates for extrinsic eyeball muscles

hypoglossal nerve

this nerve is positioned more to the midline than the other cranial nerves on the medulla

Lateral Ventricles

One in each Cerebral hemisphere, extend deep into the cerebrum as horseshoe-shaped chambers

interventricular foramen

CSF circulates from the lateral ventricles through this...

third ventricle

A small chamber within the diencephalon

Mes. Cerebral Aqueduct

CSF in the third ventricle passes through this structure of the mesencephalon

Trochlear Nerve

The nerve that supplies motor fibers to the superior oblique muscle of the eye and originates where the mesencephalon joins the pons

Pons

Part of the brain that is superior to the medulla and functions as a relay station to direct sensory information to the thalamus and cerebellum

Mesencephalon

Part of the brain that is located superior to the pons. Covered by the cerebrum.

Cerebellum

Inferior to occipital lobe of the cerebrum

Penial Gland

A nipple like structure superior to the mesencephalon positioned between the cerebrum and the cerebellum

Motor nerves

Cranial nerves that primarily conduct motor commands

Trigeminal Nerve

The largest cranial nerve

Septum pellucidum

It is a thin membrane that separates the lateral ventricles

fornix

The inferior portion of the corpus callosum

Abducens nerve

Nerve that controls the lateral rectus extrinsic muscle of the eye

Facial Nerve

Nerve located on the medulla oblongata, posterior and lateral to the abducens nerve

Vestibulocochlear Nerve

This nerve is also called the auditory nerve, is a sensory nerve of the inner ear located on the medulla oblongata near the facial nerve

Diencephalon

Part of the brain that is embedded in the cerebrum and is visible only from the inferior aspect of the brain

Glossopharyngeal nerve

A mixed nerve of the tongue and throat

Vagus Nerve

This nerve is a complex nerve on the medulla oblongata that has mixed sensory and motor functions

Corpus Callosum

The cerebral hemispheres are connected by a thick tract of white matter called this

Accessory Nerve

This nerve is a motor nerve controlling the skeletal muscles involved in swallowing and the sternocleidomastoid and trapezius muscle of the neck
