GENERAL HISTOLOGY

Detailed explanation-1: -Sensory neurons carry impulses from the receptors in the sense organs to the CNS, while the association or connection neurons carry impulses from the sensory to the motor neurons. The motor neurons carry impulses from the CNS to the effectors.

Detailed explanation-2: -Afferent neurons, also known as sensory neurons, are the nerve fibres that bring sensory information from the external environment to the brain. They carry information from receptor cells to the Central Nervous System.

Detailed explanation-3: -Afferent nerve fibres conduct nerve impulses from the sensory organs to the CNS. Hence, it is also known as sensory nerve fibre.
