Explanation:

Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the body’s movements, sends and carries signals to and from the different parts of the body, and has a role in controlling bodily functions such as digestion. Nervous tissue is grouped into two main categories: neurons and neuroglia. Neurons, or nerves, transmit electrical impulses, while neuroglia do not; neuroglia have many other functions including supporting and protecting neurons.

• Sensory, or afferent neurons, relay information from the PNS to the CNS; different types of sensory neurons can detect temperature, pressure, and light.
• Motor, or efferent neurons, send signals from the CNS to the PNS; these signals provide information to sensory neurons to “tell” them what to do (e.g., initiate muscle movement).
• Inter-neurons connect sensory and motor neurons to the brain and spinal cord; they act as connectors to form neural circuits and are involved with reflex actions and higher brain functions like decision-making.
