Final answer:
The receptors for angular equilibrium are located in the crusta ampullaris of the semicircular canals, which detect rotational movements of the head and help maintain balance.
Step-by-step explanation:
The receptors for angular equilibrium are found in the crusta ampullaris of the semicircular canals. These mechanoreceptors are hair cells with stereocilia that respond to rotational movements of the head. When the head rotates, the fluid within the semicircular canals moves, and the hair cells in the crusta ampullaris bend in response to this movement. The bending of these hair cells initiates a signal that is transmitted through the vestibular ganglion and along the vestibulocochlear nerve to the brain, where it is interpreted to maintain balance and equilibrium. It is important to note that while the macula is involved in the detection of static head position and linear acceleration, it is not responsible for sensing angular movement, which is the function of the hair cells in the semicircular canals.
