WebConditions and Disorders What are symptoms of impaired olfactory nerve function? Issues that affect your olfactory system can cause: Anosmia, complete loss of smell.; Dysosmia (also called phantosmia), unpleasant or strange odors that occur spontaneously.; Hyposmia, partial loss of smell. Parosmia, distorted sense of smell. For example, familiar foods may … Web1.4 The Somatic Nervous System Introduction Too Hot to Touch Figure 1. When high temperature is sensed in the skin, a reflexive withdrawal is initiated by the muscles of the arm.Sensory neurons are activated by a stimulus, which is sent to the central nervous system, and a motor response is sent out to the skeletal muscles that control this …

FBbt:00001061: ventral neurectoderm WebA neuron is a single sensory or motor nerve cell, whereas a nerve is a bundle of neuronal fibers (axons). Cranial nerves have three types of sensory and three types of motor neurons, known as modalities. Therefore, a nerve may be composed of a combination of sensory or motor neurons (e.g., the facial nerve possesses sensory and motor neurons). canada post office address check
