trajectory.[1] The cardiac action potential differs significantly in different portions of the heart. The heart is provided with a special excitatory system and a contractile system necessary to perform this function. This differentiation of the action potentials allows the different electrical characteristics of the different portions of the heart. For instance‚ the specialized excitatory system of the heart has the special property of depolarizing without any external influence with a slow‚ positive

focusing of the image by bending or refracting the light onto the lens. 3- Sclera- its structure is the white of the eye and it is the tough outer layer and it protects the eyeball 4- Choroid- the choroids structure is underneath the sclera and it is a sheet of blood vessels. Its main function is it carries oxygen to the eye and removes carbon dioxide and wastes. The choroid also prevents light in the eye from scattering 5- Retina- the retina is a complex structure of photoreceptors (rods and cones) on

The intrinsic muscles lie entirely within the tongue‚ while the extrinsic muscles attach the tongue to other structures. The extrinsic muscles reposition the tongue‚ while the intrinsic muscles alter the shape of the tongue for talking and swallowing. Extrinsic tongue muscles‚ by definition‚ originate from structures outside the tongue and insert into the tongue. The four paired
