Which hand position describes the anatomical position of a person who is standing erect with feet forward?

In the anatomical position, a person stands erect with their feet together and pointing forward, while their palms face forward (anteriorly) as well. This position serves as a reference point for describing the orientation and location of body structures.

Ceruminous glands, found in the ear canal, secrete ear wax, also known as cerumen. This wax helps protect the ear canal by trapping dust, debris, and microorganisms, preventing them from reaching the eardrum.

The cell membrane, also known as the plasma membrane, regulates the transport of substances in and out of a cell. It acts as a selective barrier, controlling the passage of molecules and ions based on their size, charge, and lipid solubility. This regulation is essential for maintaining cellular homeostasis and ensuring that the cell's internal environment remains stable.

The anatomical structure that houses the malleus, incus, and stapes is the ear. These three small bones, also known as the ossicles, are located within the middle ear cavity. They are responsible for transmitting sound vibrations from the outer ear to the inner ear. The malleus, incus, and stapes work together to amplify and transmit sound waves, ultimately allowing for the perception of auditory stimuli.
