    - is a process projecting from the cell body of a neuron.
  4. d - these tracts are involved with:
    1.) Subconscious Proprioception
    2.)Posture, balance, and coordination of skilled movements
  5. e - integration takes place in the brain stem for this type of reflex.

  2. -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
  3. - the spinal nerve trunk runs for a short distance before branching into two large branches and a variable series of smaller branches, each large branch is called a??
    -this branch follows a specific course to different peripheral regions.
    -the 2 larges branches are:
    1.) Anterior (ventral) Ramus
    2.) Posterior (dorsal) Ramus
  4. - the roots of spinal nerves C5-C8 and T1 form this plexus.
    - this plexus provides almost the entire nerve supply of the shoulders and upper limbs.
    - Five important nerves arise from this plexus:
    1.) Axillary Nerve
    2.) Musculocutaneous Nerve
    3.) Radial Nerve
    4.) Median Nerve
    5.) Ulnar Nerve

  5. - these horns are b/w the anterior and posterior gray horns.
    - are present only in the thoracic, upper lumbar, and sacral segments of the spinal cord.
    - contain the cell bodies of autonomic motor nuclei that regulate activity of smooth muscle, cardiac muscle, and glands.

5 True/False Questions

  1. Brachial Plexus: ULNAR NERVE- this nerve supplies the muscles on the posterior aspect of the arm and forearm.

          

  2. Sensory&Motor Tracts: SPINOTHALAMIC TRACTS-Lateral & Anterior- these tracts are involved with:
    1.) Subconscious Proprioception
    2.)Posture, balance, and coordination of skilled movements

          

  3. Spinal Nerve Distribution: ROOTLETS-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

          

  4. Reflexes & Reflex Arcs: AUTONOMIC (visceral) REFLEXES- these reflexes involve contraction of skeletal muscles.

          

  5. External Anatomy of Spinal Cord: CAUDA EQUINA- arises from the conus medullaris.
    - is an extension of the pia mater that extends inferiorly and blends with the arachnoid mater and dura mater to anchor spinal cord to coccyx.
