- What structure contains cell bodies of sensory afferent neurons and axons made up of dorsal root and portion of the spinal nerves?
- Nervous System Divisions that show similar clinical signs
- Does Grey Matter contain cell bodies?
- Functions of the sacral spinal cord region?
- 3 functions of the spinal cord
- a Dorsal Root Ganglion (DRG)
- b Yes
- c 1.Sensory input and motor output for neck, trunk, limbs, and tail
2. Reflexive control of patterned movement and adjustment of glandular activity in response to local afferent input without voluntary control
3. Transmit info to and from brain
- d Muscle and Neuromuscular Junction, Peripheral Nerves, Spinal Cord Segments, Brain (Medulla, Pons, Cerebellum, Midbrain, Thalamus,and Cerebrum)
- e Innervation to perineum, external anal sphincter and parasympathetic preganglion to viscera of pelvis and urinary bladder
* Sciatic nerve receives fibers S1-2
5 Multiple choice questions
- 1. Meningeal = largely sensory
2. Dorsal = Sensory and motor
3. Ventral = Sensory and motor
4. Communicating branches = GVE and GVA
- Same as lateral = Both Ascending sensory and Descending Motor Pathways
- Dorsal Horn, Intermediate Zone, Ventral Horn and Lateral Horn
- Recruited for production of reflexes, anti gravity support, balance and voluntary movement
- Innervation to axial mm and skin of cranial cervical region
5 True/False questions
What are the 6 spinal cord segments? → Dorsal Horn, Intermediate Zone, Ventral Horn and Lateral Horn
What structure brings sensory fibers into the brain? → Dorsal Horn, Intermediate Zone, Ventral Horn and Lateral Horn
Function of lateral horn within grey matter → Motor neurons send axons through ventral root to innervate mm. fibers
Function of Ventral Horn within grey matter → Motor neurons send axons through ventral root to innervate mm. fibers
What does the lumbar spinal cord enlargement (Lumbar intumescence) contain? → 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
