Nervous System Concept Map

The nervous system is a complex network of specialized cells that transmit information throughout the body. It plays a crucial role in coordinating and controlling bodily functions, including movement, sensation, thought, and emotion.

Structure and Organization

The nervous system can be broadly divided into two main components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that connect the CNS to the rest of the body.

• Central Nervous System (CNS):The CNS is the central processing unit of the nervous system. It receives sensory information from the PNS and sends motor commands back to the body. The brain is the most complex part of the CNS, responsible for higher-order functions such as cognition, emotion, and memory.

• Peripheral Nervous System (PNS):The PNS connects the CNS to the rest of the body. It consists of two main divisions: the somatic nervous system and the autonomic nervous system. The somatic nervous system controls voluntary movements, while the autonomic nervous system regulates involuntary functions such as heart rate and digestion.

Sensory and Motor Pathways, Nervous system concept map answer key pdf

The nervous system relies on specialized neurons to transmit information. Sensory neurons receive information from the external environment and send it to the CNS. Motor neurons carry commands from the CNS to muscles and glands, causing them to contract or secrete substances.

• Sensory Pathways:Sensory pathways involve the transmission of information from sensory receptors to the CNS. These pathways consist of a chain of neurons that relay signals from the periphery to the brain.
• Motor Pathways:Motor pathways involve the transmission of commands from the CNS to muscles and glands. These pathways consist of motor neurons that carry signals from the brain to the target organs.
