A domestic cat's sense of smell is 9-16 times as strong as humans'. [17] Cats have a larger olfactory epithelium than humans (about 20 cm 2), meaning that cats have a more acute sense of smell. [18] In fact, cats have an estimated 45 to 200 million odor-sensitive cells in their noses, whereas humans only have 10 million odor-sensitive cells ...
Cats are highly territorial, and secretion of odors plays a major role in cat communication. The nose helps cats to identify territories, other cats and mates, to locate food, and has various other uses. [7] A cat's sense of smell is believed to be about fourteen times more sensitive than that of humans.
Schematic diagram of the human ear [clarification needed] The outer ear includes the pinna, the visible part of the ear, as well as the ear canal, which terminates at the eardrum, also called the tympanic membrane. The pinna serves to focus sound waves through the ear canal toward the eardrum.
Cats have an acute sense of smell, due in part to their well-developed olfactory bulb and a large surface of olfactory mucosa, about 5.8 cm 2 (0.90 in 2) in area, which is about twice that of humans. [79] Cats and many other animals have a Jacobson's organ in their mouths that is used in the behavioral process of flehmening. It allows them to ...
The vestibular-ocular reflex (VOR) is a reflex eye movement that stabilizes images on the retina during head movement by producing an eye movement in the direction opposite to head movement, thus preserving the image on the center of the visual field. For example, when the head moves to the right, the eyes move to the left, and vice versa.
The olfactory system, is the sensory system used for the sense of smell (olfaction). Olfaction is one of the special senses directly associated with specific organs. Most mammals and reptiles have a main olfactory system and an accessory olfactory system. The main olfactory system detects airborne substances, while the accessory system senses ...
Bigger (proportional real size) and full redraw (more realistic) of the auricle. Ossicles in white colour. Eardrum with contour. Added 3 labels. Add fundus to the bone and subcutaneous tissues, add superior auricular muscle, add transparency to middle ear, add separation between middle and inner ear, add division to internal auditory canal.
