Dura mater: {Ans: -Outer periosteal layer -most superficial of the three spinal meninges -thick strong layer composed of dense irregular connective tissue -surrounds spinal cord and is separated from vertebrae by epidural space}Olfactory Nerve: {Ans: -smell -sensory}Glossopharyngeal Nerve: {Ans: Sensory: -Taste, touch, pressure, pain, and temperature sensations from tongue and outer ear -regulation of blood pressure and respiration Motor: -Salivation, swallowing, gagging}spinal reflex {Ans: A simple automatic action of the spinal cord not requiring involvement of the brain, such as the knee-jerk reflex}Be able to label figure 14.2b: Ventricles and Cerebrospinal Fluid {Ans: }reflex arc components {Ans: -somatic receptors: in the skin, muscles, and tendons -afferent nerve fibers: carry information from these receptors to the posterior horn of the spinal cord or to the brainstem -integrating center: a point of synaptic contact between neurons in the gray matter of the cord or brainstem -efferent nerve fibers: carry motor impulses to the muscles -effectors: the muscles that carry out the response}
