Brain
The largest part of the brain.
What is the cerebrum!
The three main components of the nervous system.
What are The Brain, the Spinal Cord, and the Neurons
It's not "funny" when you hit this nerve near the elbow that supplies sensation and movement to the pinky and ring fingers.
What is the ulnar nerve.
The fibrous outer white layer of the eye.
What is the Sclera?
The location and major function(s) of the cerebellum.
What is the major structure of the hindbrain located at the back of the skull, beneath the occipital and temporal lobes and behind the brainstem. Known as the "little brain," it makes up roughly 10% of total brain volume but houses over half to 80% of the brain's total neurons.
Location and major function(s) of the phrenic nerve.
What nerve originates in the neck and travels through the chest past the heart and lungs, and penetrates the diaphragm to provide motor supply to the thoracic diaphragm, controlling breathing
It also carries sensory and pain fibers from the torso.
Location and major function of the femoral nerve.
originates from the lumbar plexus and travels deep to the inguinal ligament into the front of the thigh.
Innervates the anterior thigh muscles (quadriceps femoris, sartorius, iliacus) which extend the knee and flex the hip.
Supplies the anterior/medial thigh and the knee, extending down as the saphenous nerve to the medial side of the leg and ankle
A spiral-shaped, fluid-filled cavity in the inner ear that converts sound waves into electrical nerve signals.
What is the cochlea?
The three main sections of the brainstem.
What are the midbrain, Pons and medulla oblongata.
12 pairs of nerves that originate from the spinal cord and supply movement and sensation to the chest, upper back, and abdomen.
What are thoracic nerves.
Nerve originating from the lumbar plexus that innervates the medial thigh adductor muscles to pull the leg inward.
What is the obturator nerve. (adductor longus, adductor brevis, adductor magnus, gracilis, obturator externus)
The primary funtion of the lens and ciliary body (ring and processes).
What allows your eye to switch focus between distant and nearby objects?
Made up of the thalamus and hypothalamus.
What is the diencephalon.
The four lobes of the brain
What are Frontal, Temporal, Parietal, and Occipital
The brain region and primary nerve of the parasympathetic nervous system.
What are the medulla oblongata and vagus nerve that regulate unconscious functions like heart rate, breathing, and digestion across the heart, lungs, and gut.
The largest and longest single peripheral nerve in the body, running from the lower back through the hips and buttocks down each leg.
What is the sciatic nerve? It controls major lower body muscles and provides sensation to the legs and feet. Innervates the hamstring muscles (semitendinosus, semimembranosus, biceps femoris) to extend the hip and flex the knee.
A region where impulses are transmitted from nerves to another cell.
What is the synapse? (to another nerve, muscle or gland cell)

What are the 1 olfactory, 2 optic, 3 oculomotor, 4 trochlear, 5 trigeminal, 6 abducens, 7 facial, 8 vestibulocochlear, 9 glossopharyngeal, 10 vagus, 11 accessory, 12 hypoglossal
Identify the four major nerve plexuses
What are the cervical, brachial, lumbar, and sacral plexuses.
The primary nerve(s) stimulated during the muscle physiology experiments.
What are the Ulnar and Median nerves.
The name for inner layer of eye and the specific region that provides the sharpest, highest-acuity central vision in the human eye.
What is the fovea centralis (of the macula) on the retina.
List the four interconnected, fluid-filled cavities that produce and circulate cerebrospinal fluid (CSF) to cushion and protect the central nervous system.
What are the lateral ventricles, third and fourth ventricles
