The homunculus is commonly used today in scientific disciplines such as psychology as a teaching or memory tool to describe the distorted scale model of a human drawn or sculpted to reflect the relative space human body parts occupy on the somatosensory cortex (the sensory homunculus) and the motor cortex (the motor homunculus).
Ear hair is the terminal hair arising from folliculary cartilage inside the external auditory meatus in humans. [1] In its broader sense, ear hair may also include the fine vellus hair covering much of the ear, particularly at the prominent parts of the anterior ear, or even the abnormal hair growth as seen in hypertrichosis and hirsutism .
Hair that is shaved or buzzed on the sides leaving a strip of hair in the middle. It is often spiked up. Mop-Top: A mid-length haircut that has a fringe (bangs) that brushes over the forehead, collar length at back, with the ears partly covered by the hair, dependent on style.
Ear hair generally refers to the terminal hair arising from follicles inside the external auditory meatus in humans.

Vellus hair is short, thin, light-colored, and barely noticeable hair that develops on most of a human's body during childhood. Exceptions include the lips , the back of the ear , the palm of the hand , the sole of the foot, some external genital areas, the navel , and scar tissue.
Hair is a protein filament that grows from follicles found in the dermis.Hair is one of the defining characteristics of mammals.The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair.
In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.
The stapes is the third bone of the three ossicles in the middle ear and the smallest in the human body. It measures roughly 2 to 3 mm , greater along the head-base span. [ 1 ] It rests on the oval window , to which it is connected by an annular ligament and articulates with the incus , or anvil through the incudostapedial joint . [ 2 ]
