Document Summary

Unit 5: collecting information, receptors monitor inside and outside, evaluating - decision-making, integrate sensory input, makes decisions, triggers responses, activating muscles and glands. Plexus- network of converging and diverging nerve fibers. Cutaneous region of sensation specific spinal nerve. Cardiac muscle of the heart: sympathetic or thoracolumbar, ventral roots: all thoracic and l1-3, parasympathetic or craniosacral, cn 3, 7, 9, 10 and ventral roots of s2, 3, 4. Both 2 neuron chain - ganglion between. Preganglionic neuron (cord or brain) autonomic ganglion postganglionic neuron effector neuron. Nt effect: always excitatory - stimulates contraction. Contain cell bodies of association of neurons. Synapse with sensory fibers from dorsal root. Medial part of ventral horn = proximal limb. Lateral part of ventral horn = distal limb. Divided into 3 regions: funiculus or column. Tight junctions between endothelial cells that form the capillary walls. Controls passage from blood to cells in brain. Glucose, fats, fatty acids, alcohol, o2, co2.
