Physiology 2: I & II Flashcards
Fibers of Most Nerves
Sensory + Motor
Nerves that Conduct Impulses to CNS
Sensory (Afferent)
Nerves that Conduct Impulses Away from CND
Motor (Efferent)
Nerves from the Neck Down
General
Nerves within the Head
Special
Nerves that Stimulate Skeletal Muscles
Somatic
Nerves that Stimulate Smooth Muscle and Organs
Visceral
Most Simple Nerve Pathway
Sensory Neuron - Interneuron - Motor Neuron
Reflex Arc
Reflex Arc Characteristics
- Automatic
- Subconscious
- Helps Maintain Homeostasis
- Involuntary
Tracts that Conduct Sensory Impulses to the Brain
Ascending
Tract that conducts sensory impulses of pain, temperature, and pressure and touch from various body regions
Spinothalamic
Tracts that Conduct Motor Impulses from the Brain
Descending
Tract that conducts motor impulses to various skeletal muscles
Corticospinal
Receptors that detect tissue damage
Nociceptors
Receptors that detect change in muscle/tendon
Proprioceptors
