What characteristics are common to all respiratory surfaces. Describe cooperativity as it relates to oxygen binding by the hemoglobin molecule. Examine this strength-duration curve for a nerve. Determine the rheobase and chronaxie. Provide some evidence to support this claim.
Invertebrates increase conduction velocity by increasing fiber diameter.
Assume that each myelin layer contributes a capacitance of Cm. Receptors of the eye respond to a stimulus by hyperpolarizing rather than depolarizing. Yet this poses no problem in generating an action potential in the ganglion cell. An arrow spans the entire horizontal extent of the visual field and the fixation point is imaged onto each fovea. Describe the image formed on each retina and which portion of the visual space is mapped onto the left and right lateral geniculate nucleus.
