- Spinal Nerve Branches: ANTERIOR (ventral) RAMUS
- a - contain somatic motor nuclei, which are clusters of cell bodies of somatic motor neurons that provide nerve impulses for contraction of skeletal muscles.
- b - this nerve supplies the deltoid muscles and teres minor muscles.
- c - this is a somatic branch that runs in the musculoskeletal wall of the body.
- this branch serves the muscles and structures of the upper and lower limbs and the muscles and skin of the lateral and anterior regions of the trunk.
- d - the roots of spinal nerves (anterior rami) S4-S5 for this small plexus.
- supplies a small area of skin in the coccygeal region.
- e - the axon and its associated glial cells form this.
- is a process projecting from the cell body of a neuron.
5 Multiple choice questions
- -these are three connective tissue coverings that encircle the spinal cord and brain.
-from superficial to deep they are:
1.) Dura Mater
2.) Arachnoid Mater
3.) Pia Mater
- - this pathway includes:
1.) Lateral Corticospinal
2.) Anterior Corticospinal
3.) Corticobulbar Tracts
- they convey nerve impulses that originate in cerebral cortex destined to cause precise, voluntary movements of skeletal muscle.
- - this nerve supplies most of the muscles of the anterior forearm.
- - this nerves supplies the anteromedial muscles of the forearm and most of the muscles of the hand.
- - these reflexes involve contraction of skeletal muscles.
5 True/False questions
Sensory&Motor Tracts: SPINOTHALAMIC TRACTS-Lateral & Anterior → - these tracts convey nerve impulses for sensing pain, temperature, itching, tickling, deep pressure, and a crude, poorly localized sense of touch.
Lateral: sense Pain and Temperature
Anterior: sense Crude touch and Deep Pressure
Spinal Nerve Branches: RAMUS → - these are components of the autonomic nervous system(ANS)
Protective Coverings of the Spine → - the first line of defense are the skull and vertebral column. vertebral column surrounds spinal cord providing as strong protective cases.
- second line of defense is the Meninges, which are 3 protective membranes that lie b/w the bony encasement and nervous tissue.
- Finally, central nervous tissue "floats" in Cerebrospinal Fluid, which cushions both the brain and spinal cord.
Spinal Nerve Branches: RAMI COMMUNICANTES → - these are components of the autonomic nervous system(ANS)
Brachial Plexus: RADIAL NERVE → - this nerve supplies the muscles on the posterior aspect of the arm and forearm.
