Question

name and define the two types of impulses sent through the cranial and spinal nerves of the peripheral nervous system.

Explanation:

The two types of impulses in the peripheral nervous system's cranial and spinal nerves are sensory (afferent) and motor (efferent) impulses. Sensory impulses carry information from sensory receptors to the central nervous system. Motor impulses transmit signals from the central nervous system to muscles or glands to initiate actions.

Answer:

1. Sensory (Afferent) Impulse: Carries information from sensory receptors (like those for touch, sight, etc.) to the central nervous system (brain and spinal cord).
2. Motor (Efferent) Impulse: Transmits signals from the central nervous system to muscles (to cause movement) or glands (to trigger secretions).
