Nervous System Differences according to: Motor neurons Sensory neurons Autonomic neurons Function Transmits impulses from the CNS which consists of the brain and spinal cord to muscles and glands elsewhere in the body Transmits impulses inwards from the sense organs to the CNS Located within the CNS‚ they transmit the electrical impulses generated by the stimuli to other nerves Structure Have Dendrites‚ Cell Body‚ Myelin Sheath‚ Node of Ranvier and Synaptic Knobs.

Contrast the simplicity of the neural pathways involved in reflexes with the complexity of neural networks. The Brain (pp. 58-80) 6. Identify and describe several techniques for studying the brain. 7. Describe the functions of the brainstem‚ thalamus‚ cerebellum‚ and limbic system. 8. Identify the

peripheral nervous system is divided into two major parts‚ somatic and autonomic nervous system. The somatic nervous system is made up of nerves that connects to voluntary skeletal muscles and to sensory receptors. Theses nerves cars information using the skin‚ muscles and joint to pass on to the central nervous

NERVOUS SYSTEM The nervous system consists of the brain‚ spinal cord‚ sensory organs‚ and all of the nerves that connect these organs with the rest of the body. Together‚ these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions
