NERVOUS SYSTEM I CNS (Central Nervous System) Segmentation PNS (Peripheral Nervous System) Spinal Nerves Neuron Types Autonomic Nervous System (how many nervous systems are there anyways? ) Medical ppt http: //hastaneciyiz. blogspot. com Human Anatomy, Larry M. Frolich, Ph. D.
Central Nervous System (CNS) Brain and Spinal Cord “Command Central” PNS (Peripheral Nervous System) are nerves that go out to targets in body Human Anatomy, Larry M. Frolich, Ph. D.
Coronal Section Cartoon Brain Cranial Cavity of Skull Spinal Cord Vertebral Arches Cranial Nerves I-XII (off brain) Spinal Nerves n n C--8 prs (L, R) T--12 prs L--5 prs S--5 prs Human Anatomy, Larry M. Frolich, Ph. D.
Counting Body Segments (vertebrae versus nerves) Why are there seven cervical vertebrae but eight cervical nerves? Human Anatomy, Larry M. Frolich, Ph. D.
Transverse View (x-section) vertebral body vertebral arch vertebral foramen spinal cord Human Anatomy, Larry M. Frolich, Ph. D.
Sagittal View vetebral body, arch intervertebral disc spinal cord spinal nerves (where? ) Human Anatomy, Larry M. Frolich, Ph. D.
Zebra-Man Dermatomes Each is sensory area of one spinal nerve Human Anatomy, Larry M. Frolich, Ph. D.
Peripheral Nervous System (PNS) Sensory/Afferent (info. In) Motor/Efferent (commands out) Somatic Visceral/Autonomic --smooth mm. --heart --glands Parasympathetic Sympathetic (hint: SAME) All nerves that leave the CNS Two Modalities: Human Anatomy, Larry M. Frolich, Ph. D.
