A and E of cranial n
Afferent and Efferent fibers of cranial nerve
| Question | Answer |
|---|---|
| What are general afferent fibers | fibers that have their cells of origin in cranial sensory ganglia |
| what do general somatic afferent (GSA) fibers carry? | carry exteroceptive (i.e. pain, temp, and touch) and proprioceptive information from sensory receptors in skin, muscle, tendons, and joints |
| General visceral afferent(GVA) fibers transmit what? | transmit impulses from visceral structures (i.e. hollow organs and glands) within the head neck and in the thoracic and abdominal cavities |
| What are special afferent fibers | fibers arise from neurons found only in the ganglia of certain cranial nerves |
| special somatic afferent (SSA) fibers convey what? | convey sensory information from special sense organs in the eye and ear (i.e. vision, hearing, and equilibrium) |
| special visceral afferent (SVA) fibers carry what? | carry impulses from olfactory and gustatory receptors |
| General efferent fibers arise from what? | from motoneurons in the brain stem and autonomic ganglia |
| general efferent fibers innervate what | collectively, they innervate all musculature of the body, except the branchiomeric muscles that develop in the pharyngeal arches of the embryo |
| general somatic efferent (GSE) fibers convey what | convey motor impulses to somatic skeletal mm (myotoic origin). In the head, the somatic musculature consists exclusively of tongue muscles and extraocular muscles |
| General visceral efferent (GVE) fibers control what? | control smooth muscle and cardiac muscle and regulate glandular secretion. Parasympathetic preganglionic and postganglionic cells and fibers are components of four cranial nerves |
| Special efferent fibers innervate what? | the musculature of branchiomeric origi. Arise from selected cranial nerve nuclei in the brain stem |
| Special visceral efferent (SVE) fibers consist of what | consist of nerve componenets that innervate straited muscles derived from the branchial (pharyngeal) arches. These include muscles of the jaw, of facial expression, and of the pharynx and larynx. |
| Are SVE fibers part of the autonomic nervous system? | NO |
