Head position in space

Explanation:

The vestibular system or apparatus is a collection of structures in the inner ear that provides a sense of balance and awareness of spatial orientation. The information furnished by the vestibular system is essential for coordinating the position of the head and the movement of the eyes. There are two sets of end organs in the inner ear, or labyrinth: the three semicircular canals, which detects and respond to rotational movements (angular acceleration); and the utricle and saccule (the otolith organs) within the vestibule, which respond to changes in the position of the head with respect to gravity (linear acceleration).

The receptor cells of the otoliths and semicircular canals send signals through the vestibular nerve fibers to the neural structures that control eye movements, posture, and balance.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
