Anatomy is the study of living structures. Gross anatomy is the dissection and examination of major bodily structures. Microscopical anatomy is the study of structural components visible only using a light microscope. Anatomical dissection is required. To cut apart is the Greek ana temnein, which Theophrastus coined as “anatomy.”
It refers to a body part or cell’s involvement in the whole. Who or what caused a change in a natural selection system? A component’s function is defined as its contribution to the organism’s fitness.
Classification
Main categories:
- Human anatomy
- Animal anatomy — Zootomy
- Plant anatomy — Phytotomy
Human Anatomy
The study of mature human morphology. There are two types of gross anatomy: gross and microscopic. Gross anatomy is the study of anatomical features that may be observed without magnification. It is the study of anatomical features that are visible without magnification. Microscopical anatomy examines minute anatomical structures with magnifying equipment. It comprises histology (tissue organisation) and cytology (cell organisation) (the study of cells).
Human Ear Anatomy
The ear is a sensory organ. The ear is made up of:
External ear, including:
- PINNA/AURICULUM The ear’s exterior.
- External auditory tube The tube that connects the outer and middle ears.
Tympani (eardrum): The tympanic membrane denotes the distinction between the middle and outer ears.
Middle ear (tympanic cavity):
- Ossicles: Three tiny bones that attach to the inner ear and transmit sound waves. The bones are:
- Malleus
- Incus
- Stapes
- Eustachian tube: The back of the nose connects the middle ear. The Eustachian tube helps equalise middle ear pressure. Sound waves need equalised pressure to travel properly. The eustachian tube, like the nose and throat, is mucous lined.
Inner ear:
- Cochlea. This contains the nerves for hearing.
- Vestibule. This contains receptors for balance.
- Semicircular canals. This contains receptors for balance.
