Sensory Systems. How many different sensory receptors are hard at work during a roller coaster ride?
General Organization CNS (Brain + Spinal Cord) Peripheral NS (= PNS) Afferent Efferent Somatic Autonomic Sympathetic Parasympathetic.
I. Sensation A. Coding of signals into action potentials 1. receptor cells.
The Physiology of Vision part 2. Defects of image forming 1- Hyperopia ( farsightedness) : -Is a defect in which the eye-ball is shorter than normal.
Generator Potentials, Synaptic Potentials and Action Potentials All Can Be Described by the Equivalent Circuit Model of the Membrane PNS, Fig 2-11.
Membrane Potentials That Act as Signals Two types of signals Graded potentials oIncoming short-distance signals oShort-lived, localized changes in membrane.
