Nervous System in General
The system in which receptor cells transform stimuli into nerve impulses.
What is Nervous System?
The branch of spinal nerves that supply structures that course posteriorly and innervate the deep back muscles and give cutaneous innervation to the skin of the back.
What are Dorsal Rami?
The number of nerves given off by the Brachial Plexus.
What are 16 nerves?
The plexus that supplies the tissues and musculature of the pelvis, gluteal region, posterior thigh, the entire leg, and all the foot.
What is Sacral Plexus?
The types of neurons found in the dorsal root ganglion.
What are sensory neurons?
The gap between the axon terminal on one neuron (presynpatic neuron) and the dendrite of another (postsynpatic neuron).
What is Synapse?
The number of pairs of Cervical Spinal Nerves.
What are 8 pairs of Sacral Spinal Nerves?
The nerve that is derived from the ventral rami of C5-T1, a continuation of the posterior cord, and innervates posterior arm and forearm muscles.
What is Radial nerve?
The innervation of the nerve that innervates a majority of the medial thigh muscles.
What are Ventral Rami of L2, L3, and upper division of Ventral Ramus of L4?
The contents of the epidural space.
The pattern in which nerve impulses jump from node to node as they travel down the axon.
What is saltatory conduction?
The spinal nerve that courses directly inferior to lumbar vertebrae L4.
What is spinal nerve L4?
The nerve that Musculocutaneous nerve canges its name to as it courses lateral to the tendon of insertion of the biceps brachii muscle.
What is Lateral Antebrachial Cutaneous Nerve (LAC)?
The muscle that the Lumbar Plexus is within the substance of along the posterior wall of the abdomen.
What is Psoas Major?
The three layers of meninges and their spaces from superificial to deep.
What are Epidural Space, Dura Mater, Arachnoid Mater, Subarachnoid Space, and Pia Mater?
The alternate name of the cells that form fatty myelin sheaths around the axons of neurons within the PNS only.
What are Neurolemmocytes?
The regions that the Cervical Plexus supplies cutaneous innervation to.
What are neck and sides of the head?
The roots of the nerve that courses through the medial surface of the arm within the neurovascular compartment to innervate majority of muscles in the anterior forearm.
The nerve that eventually bifurcates into those that supply the majority of the musculature on the plantar surface of the foot.
What is Tibial Nerve?
The areas in which the spinal cord presents enlargements.
What are Cervical and Lumbosacral regions?
The neuroglia that are found within the central nervous system (CNS).
What are Oligodendrocytes, Microglia, Astrocytes, Ependymal cells?
The roots for the nerve that innervates the primary muscle involved in respiration.
What are Ventral Rami of C3, C4, C5?
The specific branch that innervates that skin of the medial surface of the palm, dorsum of the hand, distal end of digit 5, and medial half of digit 5.
What is Superficial Branch of the Ulnar Nerve?
The nerves and their roots of those that innervate the lateral rotator muscles.
What is...
- Nerve to Piriformis (Ventral Ramus of S2)
- Nerve to Superior Gemellus and Obturator Internus (Ventral Rami of L5, S1, S2)
- Nerve to Inferior Gemellus and Quadratus Femoris (lower division of Ventral Ramus of L4 and Ventral Rami of L5 and S1)
The vertebral level of the end of the spinal cord and the structure that descends inferior to it.
What are LV2 and Cauda Equina?
