What are the 4 major nerve plexuses?
Definition
  1. Cervical
  2. Brachial
  3. Lumbar
  4. Sacral
Term
Phrenic Nerve
Definition
Originates in the neck (C3-C5) and passes down between the lung and heart to reach the diaphragm. It is important for breathing, as it passes motor information to the diaphragm and receives sensory information from it.
Term
Phrenic Nerve: Location
Definition
[image]
Term
Axillary Nerve
Definition
Originates from the brachial plexus (upper trunk, posterior division, posterior cord) at the level of the axilla (armpit) and carries nerve fibers from C5 and C6
Term
Axillary Nerve: Location
Definition

Term
Femoral Nerve
Definition
Largest nerves in your leg. Located near the groin, it controls the muscles that help straighten your leg and move your hips, and also provides feeling in the lower part of your leg and the front of your thigh.
Term

Term
Sciatic Nerve
Definition
Nerve extending from the lower end of the spinal cord down the back of the thigh, and dividing above the knee joint

Sclera
Definition
the white outer layer of the eyeball. At the front of the eye it is continuous with the cornea

Term
Choroid Diagram
Definition

Term
Retina
Definition
a layer at the back of the eyeball containing cells that are sensitive to light and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is formed.
Term
Retina Diagram
Definition

Term
Macula Lutea
Definition
an oval yellowish area surrounding the fovea near the center of the retina in the eye. It is the region of greatest visual acuity.
Term
Macula Lutea Diagram
Definition

Term
Fovea Centralis
Definition
a small depression in the retina of the eye where visual acuity is highest. The center of the field of vision is focused in this region, where retinal cones are particularly concentrated.
Term

Term
Optic Nerve
Definition
each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.
Term

Term
Optic Disk
Definition
the raised disk on the retina at the point of entry of the optic nerve, lacking visual receptors and so creating a blind spot.

Cochlea
Definition
the spiral cavity of the inner ear containing the organ of Corti, which produces nerve impulses in response to sound vibrations.
Term

Term
Semicircular Canals
Definition
three fluid-filled bony channels in the inner ear. They are situated at right angles to each other and provide information about orientation to the brain to help maintain balance.
