1. Biot’s respiration named after Camille Biot is an abnormal ataxic breathing pattern, where rapid series of shallow respiration are followed by a period of apnea. In order to known how AMP kinase, knock down leads to Biot respiration in mice; it is necessary to known how AMP kinase affects respiratory rate. AMP kinase is a metabolic sensor and is activated in response to stretching of the lung alveolar cells and other stressors. During respiration, the lung goes through cycles of expansion and contraction (Budinger et al., 2008). When the alveolar cells stretch during expansion, the 5′ AMP-activated ...

Vestibular Projections

Vestibular projections in the central nervous system consist of vestibular end organs which communicate with the brain stem and the cerebellum via the vestibular branch of the eighth cranial nerve. These nerves are also connected to the auditory fibers. Thus damage caused to these structures can cause both vestibular and auditory disturbances. The vital function of the vestibular system is to coordinate head and eye movements. The ability of the eye to stay focused on an object even while the head is moving is brought about by the vestibular system.

Vestibular Cochlear Nerve

The vestibulo cochlear nerve or the auditory nerve is ...

The brain regulates the choice of a person to be physically active. Stimuli from the environment and from the tissues excite receptors and nerves which in turn excite the muscles. The central nervous system has three general areas that are associated with the complexity of the movement and the familiarity of the various stimuli. The areas include the spinal cord which handles simple reflex actions, the lower brain which organizes more complex responses while the cerebral cortex controls the most complicated responses and stores general motor programs. The spinal cord consists of two-way tracks of nerve fibers which carries both ...
