3. Ventral = Sensory and motor
4. Communicating branches = GVE and GVA
5 Multiple Choice Questions
- Same as lateral = Both Ascending sensory and Descending Motor Pathways
- Innervation of regional axial mm and skin, skin and mm of pelvic limb = Pelvic Plexus
* Partial Supply to bladder and perineum
- Innervation of regional mm and skin
Preganglionic sympathetic neurons
- Receive, process and relay afferent info from the dorsal root fibers
- Dorsal and ventral roots of spinal nerves that compose the pelvic plexus and attach to the spinal cord segments.
* Supplies sensory and motor innervation to the pelvic limb
5 True/False Questions
Function of Lateral Funiculi within white matter? → Both Ascending sensory and Descending Motor Pathways
3 functions of the spinal cord → Innervation to perineum, external anal sphincter and parasympathetic preganglion to viscera of pelvis and urinary bladder
* Sciatic nerve receives fibers S1-2
What are the clinical signs seen when peripheral nerves are damaged? → Paresis, Paralysis, Atrophy of muscles, Decreased sensation to cutaneous zones and decreased or absent reflexes
Function of Ventral Horn within grey matter → Motor neurons send axons through ventral root to innervate mm. fibers
Nervous System Divisions that show similar clinical signs → Innervation of regional axial mm and skin, thoracic limb mm and skin = Brachial plexus
* Contain preganglionic sympathetic innervation to eye (T1-3)
