System Containing Brain and Spinal Cord
|
CNS- Central Nervous System
(PNS is area outside brain and spinal cord) |
|
|
ANS- Autonomic Nervous System is broken down into 2 divisions; name the divisions listing two words describing each.
|
Sympathetic- fight or flight
parasympathetic- rest and digest |
|
|
What does the SNS control?
|
Skeletal muscle
|
|
|
Name the 2 horns of the "H" shaped gray matter.
|
Dorsal Horn (contains sensory axon and association neuron) and Ventral Horn (contains cell bodies of neuron)
|
|
|
What horn is found only in the thoracic region?
|
Lateral Horn (contains cell bodies of sympathetic and motor neurons)
|
|
|
Name the 4 neuronal plexus
|
cervical plexus, brachial plexus, lumbar plexus and Sacral Plexus
|
|
|
From which nerves does the cervical plexus originate?
|
The cervical plexus originates from C1-C5.
|
|
|
From which nerves does the brachial plexus originate?
|
The brachial plexus originates from C5-C8 and T1.
|
|
|
From which nerves does the Lumbar plexus originate?
|
The lumbar plexus originates from L1-L4, and sometimes T12.
|
|
|
What is the cell type for motor Nerves? Where are the cell bodies found?
|
Motor nerves are efferent, multipolar nerves whose cell bodies are found in the dorsal horn.
|
|
|
What is the cell type for sensory nerves? Where are the cell bodies found?
|
Sensory nerves are afferent unipolar nerves whose cell bodies are found in the dorsal root ganglia.
|
|
|
How do axon routes travel for sensory nerves?
|
Sensory nerves travel through the root to the dorsal horn.
|
|
|
What are the two divisions of the motor division of the PNS.
|
The PNS is divided into Autonomic nervous system and the Somatic Nervous System.
|
|
|
Where are the cell bodies of the somatic nervous system?
|
The cell bodies of the somatic nervous system are found in CNS contained within the vental horn of the spinal cord.
|
|
|
Where are the preganglionic cell bodies of the Sympathetic Division and Parasympathetic Division (of the ANS)found?
|
Ventral horn of Spinal Cord
