Unilateral loss indicates a possible nerve lesion or deviated septum. This test is usually skipped on a cranial nerve exam. [1] The short axons of the first cranial nerve regenerate on a regular basis. The neurons in the olfactory epithelium have a limited life span, and new cells grow to replace the ones that die off.
A neurological examination is the assessment of sensory neuron and motor responses, especially reflexes, to determine whether the nervous system is impaired. This typically includes a physical examination and a review of the patient's medical history , [ 1 ] but not deeper investigation such as neuroimaging .

Winter is finally here, and bears are getting ready to find a den to hibernate in over the next few months. In Wyoming's Yellowstone National Park, one bear was caught prepping for his long sleep ...
Glutamate released from the upper motor neurons triggers depolarization in the lower motor neurons in the anterior grey column, which in turn causes an action potential to propagate the length of the axon to the neuromuscular junction where acetylcholine is released to carry the signal across the synaptic cleft to the postsynaptic receptors of the muscle cell membrane, signaling the muscle to ...
Madi, Mike, and Willie must learn about getting fit from a fitness expert who demonstrates the three components of exercise: aerobic activity, strength training, and flexibility. Then, they head outdoors to design a workout for their families using simple objects from around the house.
