Final answer:
Sensory neurons (afferent neurons) carry nerve impulses from sensory receptors to the central nervous system. Motor neurons (efferent neurons) transmit nerve impulses from the central nervous system to effectors like muscles and glands. Interneurons (association neurons) connect sensory neurons to motor neurons within the central nervous system.
Step-by-step explanation:
Sensory neurons, also known as afferent neurons, carry nerve impulses from the sensory receptors to the central nervous system (CNS). These neurons detect sensory information such as touch, taste, smell, sight, and sound.
Motor neurons, also known as efferent neurons, transmit nerve impulses from the CNS to the effectors, including muscles and glands. They control muscle movement and glandular secretions.
Interneurons, also known as association neurons, connect sensory neurons to motor neurons. They are responsible for relaying information between the sensory and motor neurons within the CNS, enabling communication and coordination between different parts of the nervous system.
