Question

Which nerves transmit impulses from the central nervous system to muscle cells: * a: Sensory nerves b: Motor nerves c: Relay nerves d: Cranial nerves

Answer 1

Answer: Motor Nerves

Explanation: Motor neurons carry nerve impulses from the brain and spinal cord to muscles and glands. Interneurons carry nerve impulses back and forth between sensory and motor neurons.

Answer 2

Motor nerves transmit impulses from the central nervous system to muscle cells. (Option b)

• Motor nerves are the nerves that carry signals from the brain and spinal cord to all the glands, organs, and muscles in the human body.
• It is these motor nerves that directly control all movements associated with the muscles.
• Voluntary movement contractions are controlled by the alpha motor nerves.
• Muscle contractions occurring due to external forces are controlled by the gamma motor nerves.
• Any damage to these motor nerves can lead to muscle weakness.
