hard to walk up three stairs‚ just do it! My nerves nailed me to the auditorium floor. The thought of singing a solo in front of an audience and a judge made my heart pound‚ hands quake‚ knees shake‚ and stomach flip. My choir director‚ Ms. Ploof‚ prepared me well for the singing portion of the contest‚ but failed to warn me about these horrible nerves. Seconds passed. Then a minute went by‚ and I still stood there. With everything in me‚ I forced my nerves away as I pulled my right leg off of the ground

HUMAN BRAIN The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The human brain is the command centre for the human nervous system. It receives input from the sensory organs and sends output to the muscles. Parts of the Human Brain Ventricles are the 4 cavities in the brain. • The ventricles of the brain are a communicating network of cavities filled with cerebrospinal

These non-encapsulated nerve endings‚ located in the adventitial layer of arteries‚ are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure. Afferents from the carotid region form the fine carotid sinus nerve which ascends into the glossopharyngeal nerve (9th cranial nerve). Afferents from the aortic region form the aortic (depressor) nerve before ascending into the vagus (10th cranial nerve). These cranial nerves terminate in the nucleus

brain is to convey messages to different parts of the body. Messages are conveyed from a nerve cell to another nerve cell‚ muscle cell‚ or a gland. The messages are in the form of electrical signals called neurotransmitters. Neurotransmitters are chemicals that are released from a nerve cell that relay a message. Examples of neurotransmitters are acetylcholine‚ norepinephrine‚

than CNS neurons‚ so the chances of his neurons regenerating increase. Nerve generation depends on location of the injury‚ inflammatory responses‚ and the process of scarring. When nerves are cut‚ they often form connective tissue scars that block or slow regenerating axonal branches. This process of the nerves “healing” is called Wallerian degeneration. This is a neurological cellular is a process that results when a nerve fiber is cut or crushed (in this case severed)‚ in which the part of the

Polarization of the neuron’s membrane: cell membrane is surrounded by neurons as other cell has a membrane. If a nerve cell is not stimulated‚ the membrane is known to be polarized. For a neuron to be polarized‚ it is by maintaining excess of sodium ions on the outside of the cell and excess potassium ions on the inner part of the cell. A volume of sodium ions and potassium ions usually leaks through its channel but the sodium ions and potassium ions pumps on the membrane that restores the (k+) back

The tester should be placed on the tooth surface adjacent to a pulp horn (highest density of nerve fibres). According to Lin and co-workers (2007)‚ the optimum site of tester placement on molars is the mesiobuccal cusp tip. An ionic shift in dentinal tubule fluid causes local depolarisation and action potential generation from intact Aδ nerves‚ giving a positive result where the patient feels warmth or a tingling sensation. Reproducibility may be compromised due to
