In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and shares no field of view between them, like in some ...
the dorsal region encompassing the upper back; the lumbar region encompassing the lower back. the sacral region occurring at the end of the spine, directly above the buttocks. The regions of the back of the arms, from superior to inferior, include the cervical region encompassing the neck, the acromial region encompassing the shoulder,
[12] [13] It is an area of 4.17 steradians or 13700 square degrees for binocular vision. [14] When viewed at large angles from the side, the iris and pupil may still be visible by the viewer, indicating the person has peripheral vision possible at that angle. [15] [16] [17]
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
The lingual gyrus is the hypothetical location of V4 in macaque monkeys. In humans, this area is called hV4. The fusiform gyrus is the hypothetical location of V4α, a secondary area for colour processing. More: Colour centre. Visual area V4 is one of the visual areas in the extrastriate visual cortex.
Vision loss is typically sudden and most commonly occurs upon waking up in the morning. This condition is most common in diabetic patients 40–70 years old. Other optic nerve problems are less common. Optic nerve hypoplasia is the underdevelopment of the optic nerve resulting in little to no vision in the affected eye. Tumors, especially those ...
Distribution of rods and cones along a line passing through the fovea and the blind spot of a human eye [1]. A blind spot, scotoma, is an obscuration of the visual field.A particular blind spot known as the physiological blind spot, "blind point", or punctum caecum in medical literature, is the place in the visual field that corresponds to the lack of light-detecting photoreceptor cells on the ...
In human anatomy, the five vertebrae are between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the thoracic region).
