Document Summary
Chapter 13 notes: spinal cord, cranial nerves, and somatic reflexes. Conduction: contains bundles of nerve fibers that conduct info up and down cord, sensory info reaches brain, motor info reaches effectors. Neural integration: spinal neurons receive input, integrate it, and execute the output. Locomotion: central pattern generators- produce sequence of outputs that cause alternating movements of limbs (like walking, walking involves repetitive contractions of several muscle groups. Reflexes: posture, motor coordination, protective responses to pain and injury. Fibrous membranes enclosing brain and spinal cord. Separate soft tissue of cns from bones of vertebrae and skull. The spinal cord consists of two kinds of nervous tissue called gray and white matter. White matter: bright white color, abundance of myelin, composed of bundles of axons, called tracts, that carry signals from one level of. Cns to another: abundance of glial cells. While traveling up, the sensory signals usually travel across three neurons. First-order neuron-detects stimulus and transmits signal to spinal cord/brainstem.
