Respuesta
-
hypogastric nerves
-
pelvic splanchnic nerves
-
pudendal nerves
-
sacral splanchnic nerves
Pregunta 13
Pregunta

Pregunta 14
Pregunta
Choose the statement that does not accurately reflect the differences between the somatic and autonomic motor systems.
Respuesta
-
Somatic nerve fibers are fast-conducting; autonomic fibers are slow-conducting.
-
Somatic leads to heart muscle; autonomic leads to skeletal muscle.
-
Somatic impulses are excitatory only; autonomic impulses are excitatory or inhibitory.
-
Somatic receptors have a specialized motor end plate; autonomic receptors do not.
Pregunta 15
Pregunta
Which is the true statement regarding the sympathetic nervous system?
Respuesta
-
Both preganglionic and postganglionic fibers are myelinated.
-
Preganglionic neurons exit the spinal cord in the cervical and sacral regions.
-
Adrenal medulla cells are derived from modified postganglionic sympathetic neurons.
-
The sympathetic nervous system is rarely activated as a unit.
