The retina is a thin tissue layer located at the back of the eyeball near the optic nerve. This tissue is supplied with nutrients and oxygen by the choroid, and contains the photoreceptor cells rods and cones.Answer and Explanation: The correct answer is optic canal. The nerve ...
Neuroimmunology is one of the fastest-growing fields in the life sciences, and for good reason; it fills the gap between two principal systems of the organism, the nervous system and the immune system. Although both systems affect each other through bidi
Parts in the bodythat use or are affected by acetylcholineare referred to as cholinergic. ... Acetylcholine is also a neurotransmitter in the autonomic nervous system, both as an internal transmitter for the sympathetic nervous system and as the final product released by the parasympathetic nervous ...
Where are arachnoid villi located? a) in the central canal and cerebral aqueduct b) between the hypothalamus and the pituitary gland c) In the ventricles of the brain d) in the superior sagittal sinus. In what region of the brain...
when there is a mismatch it can make corrections to the motor program so that the body will execute what the brain wants. The balance of the two parallel pathways that synapse on the Purkinje cells determines the DCN activity, which can be suppressed or enhanced via disinhibition. The molecula...

Testosterone is a male sex hormone. This hormone is responsible for the development of male reproductive tissue (prostate, testes, etc) as well as males secondary sexual characteristics including body hair growth, and increased muscle and bone mass,...
In the rosettes, photoreceptors are located in the inner layer, preventing them from building proper synaptic connections with the host. One possible reason is the large size of retinal sheets restricting the rotation and migration of the graft, while transplanted single cells can easily adjust ...
