Answer 31

Sensory Ganglia and Autonomic/Motor/Visceral Ganglia

Question 32

What are the two types of sensory ganglia?

Answer 32

Spinal Nerve Ganglia (Dorsal Root Ganglia)

Cranial Nerve Ganglia (CN V, VII, VIII, IX, X)

Question 33

What are the two types of autonomic ganglia?

Answer 33

Sympathetic and Parasympathetic

Question 34

Where are sensory ganglia nerve cell bodies of both cranial and spinal nerves found?

Answer 34

Located in sensory ganglia outside of the CNS

Question 35

Where are autonomic ganglia nerve cell bodies found?

Answer 35

Located in motor or visceral ganglia found outside the CNS (paravertebral ganglion)

Question 36

Where is the lateral horn found and what is it?

Answer 36

Lateral horn is present in T1-L2 and is the source of preganglionic cell bodies of multipolar neurons for the autonomic nervous system

Question 37

Dorsal Horn contains:

Answer 37

multipolar neurons that send axons to multipolar neurons at higher levels in the CNS or in the ventral horn (interneurons)

Question 38

Intermediolateral Cell Column

Answer 38

Lateral Horn - found only in the thoracic and upper lumbar spinal cord (T1-L2)

Question 39

Alpha Motor Neurons

Answer 39

Innervate extrafusal skeletal muscle fibers/cells (lower motor neurons)

Question 40

Gamma Motor Neurons

Answer 40

Innervate intrafusal muscle fibers/cells of neuromuscular spindle

Question 41

Anterior Horn

Answer 41

Ventral Motor multipolar neurons that contain Alpha and Gamma motor neurons

Question 42

Dorsal Column contains:

Answer 42

ascending axons whose cell bodies are located in the dorsal root ganglia and carries the modalities of discriminative touch and proprioception.

Question 43

Lateral Column contains:

Answer 43

ascending sensory nerve tracts and descending motor nerve tracts

Sensory tracts originate in the gray matter of dorsal horn.
Motor tracts originate in upper levels of neuraxis.

Question 44

Visceral Motor System innervates:

Answer 44

smooth muscle, cardiac muscle, and glands (Autonomic Nervous System)

Question 45

Efferent Neurons contain:

Answer 45

Two neurons with the first located in the CNS, the second located in an autonomic ganglion

Question 46

What are the two major subdivisions of the Autonomic Nervous System?

Answer 46

Sympathetic and Parasympathetic

Question 47

Dorsal Ramus innervates?

Answer 47
