NOTE

NERVOUS SYSTEM

Nervous coordination refers to the process by which the nervous system regulates and coordinates the activities of different parts of the body. It involves the transmission of electrical signals, called nerve impulses, between nerve cells (neurons) to relay information and initiate appropriate responses.

Organization of the nervous system

The nervous system is organized into two main parts:

  1. Central Nervous System (CNS): It's the body's main information processing center, responsible for coordinating and controlling most functions of the body and mind. The CNS consists of the brain and spinal cord.

   - The brain serves as the command center of the body, processing sensory information, initiating motor responses, and controlling higher functions such as thought, emotion, and memory.

   - The spinal cord acts as a relay system, transmitting signals between the brain and the peripheral nervous system and coordinating reflex responses.

  1. Peripheral Nervous System (PNS): The PNS is responsible for transmitting sensory information from the body to the central nervous system (CNS) and conveying motor commands from the CNS to the muscles and glands. It includes the somatic nervous system, which controls voluntary movements and sensory perception, and the autonomic nervous system, which regulates involuntary processes like heart rate, digestion, and respiration.

   - The PNS includes all the nerves and ganglia outside the brain and spinal cord.

   - It is further divided into the somatic nervous system and the autonomic nervous system.

     - The somatic nervous system controls voluntary movements and sensory perception, transmitting signals between the CNS and the body's muscles and sensory organs.

 EVALUATION: 1. What is  nervous coordination?

  1. Discuss the organization of the nervous system.
