Presentation Transcript

  1. Somatic N.S. Autonomic N.S. Central Nervous System Peripheral Nervous System Involuntary Voluntary

  2. Somatic N.S. Autonomic N.S. Peripheral Nervous System Skeletal Muscle Parasympathetic Division Sympathetic Division Cardiac, Smooth muscle and Glands

  3. Somatic Nervous System (SNS) CNS One motor neuron to a single effector tissue: Effector Tissue Skeletal muscle Autonomic Nervous System (ANS) Two motor neurons to many effector tissues: Effector Tissue Cardiac muscle Smooth muscle and glands

  4. Somatic Nervous System (SNS) Effector Tissue is Skeletal Muscle Control is Voluntary (except reflexes) Autonomic Nervous System (ANS) Effector Tissue is Cardiac & Smooth Muscle and Glands Control is Involuntary (except biofeedback) Parasympathetic: “Rest & Digest”, Craniosacral Origins, convergent. Ganglion close to effector tissue. Sympathetic: “Fight or Flight”. Thoracolumbar Origins, divergent. Ganglion close to spinal cord.

  5. Functional components, and anatomical subdivisions.
