Smooth Muscle contractions are regulated by calcium ions. The smooth muscle differs from skeletal muscle in that its contracts from all sides.
The band is called Corpus Collasum.
CNS - central nervous system
There is no difference between plasma and cell membrane.
The Olfactory Nerve (Cranial Nerve I) controls the sense of smell.
I know the answer it is the method of the hydrocoleptic glands that detect the stimulus :)
Sensory neurones carry impulses to the CNS, motor neurones carry impulses to muscles.

Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
The pia mater is the delicate innermost layer of the meninges-the membranes surrounding the brain and spinal cord. It is delicate and vascular, and follows every contour of the brain.
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
The zoster virus is what causes herpes zoster or shingles.
Vision reception is processed in the occipital lobe (at the back of the brain), with visuospatial processing occurring in the parietal lobe.
the cells involved in most nervous system tumors are called
sympathetic nervous system
A positive ion (cation) that enters the cell (influx) rapidly when the membrane threshold is reached and the voltage gated sodium channels open.
This occurs during the rising phase of an action potential, i.e. membrane depolarization beyond the threshold for activation.
structural model of plasma membrane is called the selectively permeable membrane
Structural model of the plasma membrane is called
Fluid Mosaic Model.
Afferent nerves of the peripheral nervous system carry sensory information to the spinal cord.
At the ends, adjacent to the articulating surfaces.
