What is the order of these objects as it occurs in a microscope, beginning with the eye to the specimen on the stage.
AleksAgata [21]
<h2>Order of parts of a microscope </h2>

First – ocular lens

Second – Body tube

Third – Revolving Nosepiece

Fourth – Objective lens

Fifth – Coverslip

Explanation:

Ocular lens: The lens present in the eyepiece at the top of the microscope, close to the eyes, through which a person looks through the microscope to view the specimen. Magnification of ocular lens in a compound microscope is usually 10x

Body tube: The tube that connects the eyepiece with the objective of the microscope for continuous optical alignment.

Revolving Nosepiece: The turret that holds the objective and revolves to select the objective lens according to its magnification

Objective lens: The objective lens is located above the specimen rack. Objective lens creates the primary image of the specimen viewed through the eyepiece. A single compound microscope can have more than two objective lens and their magnification ranges from 4x, 10x, 40x, 100x power.

Coverslip: The cover glass which covers the objective lens and prevent from touching the specimen . This is the object directly above the specimen.

The outer hair cells change length in response to basilar membrane motion. What does that accomplish?
olga nikolaevna [1]

Outer hair cells change their axial dimensions in response to electrical stimulation.

What is basilar membrane motion?

Hair cell stereocilia move as a result of the basilar membrane's movement. The tectorial membrane and the hair cells, which are connected to the basilar membrane, move along with it when it moves, and the stereocilia bend in response to the relative motion of the tectorial membrane.

The hair cells that are linked to the auditory nerve fibers are stimulated by the basilar membrane's movement. While the outside hair cells actively affect the basilar membrane's vibrations, the inner hair cells convert hydromechanical vibration into action potentials.

With each sound cycle, the intracellular voltage of the outer hair cells varies, causing them to lengthen and contract. This increases the organ of Corti's vibration, enabling exceptionally high hearing sensitivity and frequency selectivity.
