- What are the clinical signs seen when peripheral nerves are damaged?
- What does the cervical spinal cord enlargement (cervical intumescence) contain?
- Function of Ventral Funiculi within white matter?
- What are the 3 bilateral column fibers within white matter?
- T/F. White Matter contains dorsal and ventral root fibers.
- a Same as lateral = Both Ascending sensory and Descending Motor Pathways
- b Paresis, Paralysis, Atrophy of muscles, Decreased sensation to cutaneous zones and decreased or absent reflexes
- c 1. Dorsal Funiculi
2. Lateral Funiculi
3. Ventral Funiculi
- d True
- e Dorsal and ventral roots of spinal nerves that compose the brachial plexus and attach to the spinal cord segments.
* Supplies sensory and motor innervation to the thoracic limb
5 Multiple choice questions
- Recruited for production of reflexes, anti gravity support, balance and voluntary movement
- False b/c the spinal cord grows @ slower rate than vertebral column
- Dorsal Root Ganglion (DRG)
- 1. Meningeal = largely sensory
2. Dorsal = Sensory and motor
3. Ventral = Sensory and motor
4. Communicating branches = GVE and GVA
- 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
5 True/False questions
What are the clinical signs seen then the femoral nerve is damaged? → Paresis, Paralysis, Atrophy of muscles, Decreased sensation to cutaneous zones and decreased or absent reflexes
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
What are the 6 spinal cord segments? → Dorsal Horn, Intermediate Zone, Ventral Horn and Lateral Horn
Nervous System Divisions that show similar clinical signs → Muscle and Neuromuscular Junction, Peripheral Nerves, Spinal Cord Segments, Brain (Medulla, Pons, Cerebellum, Midbrain, Thalamus,and Cerebrum)
Functions of cervicothoracic spinal cord region? → Innervation to perineum, external anal sphincter and parasympathetic preganglion to viscera of pelvis and urinary bladder
* Sciatic nerve receives fibers S1-2
