Question

1. the neurons that relay information to the effector organs are

a) receptor neurons
b) sensory (afferent) neurons
c) motor (efferent) neurons
d) interneurons (association neurons)

1. the part of the neuron that conduct nerve impulses away from the cell body is the

a) axon
b) dendrite
c) myelin sheath
d) nodes of ranvier

Explanation:

1. Motor (efferent) neurons carry signals from the central nervous system to effector organs like muscles and glands. Receptor and sensory (afferent) neurons carry information to the central nervous system, and interneurons are within the central nervous system for processing.
2. The axon is the part of the neuron that conducts nerve impulses away from the cell - body. Dendrites receive signals, the myelin sheath insulates the axon, and nodes of Ranvier are gaps in the myelin sheath for faster impulse conduction.

Answer:

1. c) motor (efferent) neurons
2. a) axon
