Document Summary

Autonomic nervous system controls almost every essential body process. Motor division of the pns to cardiac muscle, smooth muscle and glands. Bothdivisions counterbalance to increase/decrease e ector organ function (variability in receptor subclass in organ) Hypothalamus = boss, regulates autonomic e erent nerve activation. Limbic system (emotional senses and memories) can trigger hypothalamus physiological responses to emotion. Spinal cord mediates autonomic re exes bladder and bowel. Photoreceptors are located in the __retina (neural layer)__, which is the __sensory____ layer of the eye. The mucous membrane that lines the eyelids is called __conjunctiva_____. Connective tissue plates that support the palpebrae are called __tarsal plates__. Compare and contrast the functions of rods and cones. Rods: more rods than cones, used for periphery, respond to dim light (not sensitive) Cones: more sensitive, respond to bright light, high acuity of colour, fovea centralis: only cones, maculae lutea: mostly cones. Compare and contrast phototransduction in light and dark.
