Answer:

Please mark me Brainlist

Explanation:

i)Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous systme and towards muscles to cause movement.Afferent neurons convey information from tissues and organs to the brain and efferent signals transmit information from the brain to effector cells in the body. ... Interneurons connect neurons within specific regions of the central nervous system. Efferent neurons carry information away from a brain region.

ii)CENTRAL NERVOUS SYSTEM

The CNS Is connected to sensory receptors, muscles and glands in Peripheral parts of the body by the Peripheral nervous system.

PERIPHERAL NERVOUS SYSTEM

The sensory neurons contract nerve impulses from sensory receptors in various parts of the body to the central nervous system

iii)The key difference between receptor and effector is that receptor is a cell or a group of cells in a sense organ that receives a particular stimulus while an effector is an organ that produces a response to the stimulus. ... Sensory neurons carry these nerve impulses to the central nervous system.

Answer 2

Answer:

Afferent and Efferent nerves

• Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous systme and towards muscles to cause movement.
• Central nervous system (CNS) and Peripheral nervous system (PNP)

The CNS is made up of the brain and the spinal cord.When the sensory input reaches the CNS, the spinal cord and the brain figure outs.Once the CNS has understood the information, the PNS will relay the specific orders back out the body.

Peripheral nervous system (PNP)

The PNS is made up of all the nerves travelling from the CNS to all the organs in your body, from the skin on your scalp to the tip of your toes.The peripheral nervous system’s main job is to send information gathered by the body’s sensory receptors to the CNS as quickly as possible.The PNS has two important parts. They are the motor division and the sensory division.

Receptor and effector

• The key difference between receptor and effector is that receptor is a cell or a group of cells in a sense organ that receives a particular stimulus while an effector is an organ that produces a response to the stimulus.
