Acoustic neuroma

A benign tumor of the eighth cranial nerve; more accurately referred to as a schwannoma, because it is composed of Schwann cells, which produce myelin.

Aneurysm

Dilation or ballooning of an artery wall as a result of injury, disease, or congenital condition.

Arteriovenus malformation AVG

A collection of blood vessels with abnormal communication between the arteries and veins. It may be the result of injury, infection, or a congenital condition.

Astrocytes

Cells that support the nerve cells -- neurons -- of the brain and spinal cord by providing nutrients and insulation.

Bone flap

A section of bone removed from the skull during craniotomy procedures.

Embolization

A technique used to occlude a blood vessel. A variety of materials, including platinum coils and microscopic plasrtic particles, are injected into the vessel under fluoroscopy control to stop active bleeding or prevent bleeding.

Intracranial pressure ICP

The pressure within the skull exerted by the brain tissue, blood, and cerebrospinal fluid.

Stereotactic

A computerized method of locating a point in space or in tissue, using coordinates in three dimensions. Duyring stereotactic surgery, the precise location of a tumor or other tissue can be identified from outside the body. The tissue can then be targets for destruction. The term originates from the Greek words stereo, meaning three dimensional, and tacos meaning touched.

Cranial Nerve I

OLFACTORY NERVE. Responsible for the sense of smell.

Cranial Nerve II

OPTIC NERVE Conveys impulses for sight.

Cranial Nerve III

OCULOMOTOR NERVE Controls the muscle that moves the eye and the iris.

Cranial Nerve IV

TROCHLEAR NERVE Controls the oblique muscle of the eye.

Cranial Nerve V

TRIGEMINAL NERVE A sensory nerve thgat controls the sensation of the face, forehead, mouth, nose, and top of the head.

Cranial Nerve VI

ABDUCENS NERVE SE to the lateral rectus muscle of the eye

Cranial Nerve VII

FACIAL NERVE A motor nerve that controls the muscle in the face and scalp.

Cranial Nerve VIII

VESTIBULOCOCHLEAR NERVE Controls hearing and equilibrium

Cranial Nerve IX

GLOSSOPHARYNGEAL NERVE Controls the sense of taste.

Cranial Nerve X

VAGUS NERVE Innervates the pharyngeal and laryngeal muscles, heart, pancreas, lungs, and digestive systems.

Cranial Nerve XI

ACCESSORY NERVE Has two parts, a a cranial portion and a spinal portion. Cranial root; joins vagus -- VA to laryngeal muscles; spinal root C1-C5; innervates trapezius and sternocleidomastoid muscles.

Cranial Nerve XII

HYPOGLOSSAL SE to extrinsic and intrinsic muscles of tongue

Efferent nerve

Think motor. Brain to ganglia. To end

Afferent

Feedback to the motor.

Afferent nerves are

in the back. The spine.

Efferent nerves are in the

front.

Oligodendrocytes form

myelin, the fatty sheath that provides insulation for the dendrites.

Choroid Plexus

Produces CSF and reabsorbs CSF

Myelography

A contrast medium is injected into the subarachnoid space for visualization of the spinal cord and nerve roots.

Nitrogen is used for

the power tools.

Closing holes in dura

you will use neurolon.

Methyl methacrylate beads

are mixed with antibiotics and inserted. Ortho uses them, too.

Octylcyanoacrylate

derma bond. Super glue used in surgery. Close the edges of the skin. Can be used for a brain aneurysm because the super glue encases it.

Craniosynostosis

Premature closure of the skull sutures. Taber's Dictionary

Laminectomy

Surgical removal of the bony arches of one or more vertebrae. It is performed to treat compression fractures, dislocations, herniated nuclear pulposus, and cord tumors and to stimulate the spinal cord. Spinal fusion with cages, rods, screws, and/or bone graft is used to stabilize the spine if several laminae are removed.

Flocculonodular

lobe help control the equilibrium

Vertebral Column

7 cervical, 12 thoracic, 5 lumbar vertebrae, 5 sacral vertebrae.
