Sensory Receptors
Senses stimuli from outside the body
What is an exteroceptor?
The type of nerve originating from the brain
What is a cranial nerve
Peripheral motor nerves release neurotransmitters at these locations in skeletal muscle.
What are neuromuscular junctions?
an example of this reflex is the simple "knee-jerk" reflex
What is a stretch reflex
This is the subsection of the peripheral nervous system associated with voluntary control of the body
What is the somatic nervous system?
These receptors detect pain
What are nociceptors?
The number of thoracic nerves
What is 12?
This word means to stimulate something with a nerve
What is to innervate
This type of reflex is monosynaptic and ipsilateral
What is a stretch reflex
A contralateral reflex that results in the extension of an opposite limb
What is a crossed-extensor reflex?
These encapsulated dendritic endings respond to deep pressure
What are Lamellar (Pacinian) corpuscles?
Where cell bodies of sensory spinal nerves are located
What is the Dorsal Root Ganglion?
Peripheral motor nerves release neurotransmitters at these locations in smooth muscle and glands.
What are varicosities?
This type of reflex is polysynaptic and ipsilateral and results when a muscle is strongly contracted
What is a tendon reflex?
The area of skin innervated by a single spinal nerve
What is a dermatome
The interpretation of a stimulus
What is perception?
This plexus contains the phrenic nerve (which innervates the diaphragm).
What is the cervical plexus
This root of a spinal nerve contains motor fibers
What is the ventral root
The process of relaxing the antagonist muscle during a stretch reflex
What is reciprocal inhibition?
This area of the brain is anterior to the central sulcus and is responsible for voluntary movements
What is the primary motor cortex
A receptor that reacts less frequently to an unchanging stimulus
What is a fast-adapting receptor?
These join the thoracic ventral rami to the sympathetic trunk of the autonomic nervous system
What are the rami communicante?
This law states: "Any nerve serving a muscle that produces movement at a joint also innervates the joint and the skin over the joint."
What is Hilton's Law
What is the plantar reflex
These proprioceptors measure muscle stretch/length
What are muscle spindles
