Within the otic capsule are the usual labyrinthine endings, including an auditory papilla. The auditory papilla lies in a path between the oval window and an opening (the round window) in the posterior wall of the otic capsule.
Human ear, organ of hearing and equilibrium that detects and analyzes sound by transduction and maintains the sense of balance. Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. Learn about the anatomy and physiology of the human ear in this article.
Other articles where optic chiasm is discussed: human eye: The visual pathway: The optic nerves after this point are called the optic tracts, containing nerve fibres from both retinas. The result of the partial decussation is that an object in, say, the right-hand visual field produces effects in the two eyes that are transmitted to the left-hand side…
Health & Medicine Anatomy & Physiology cross section of the eye Horizontal cross section of the human eye, showing the structures of the eye, the visual axis (the central point of image focusing in the retina), and the optical axis (the axis about which the eye is rotated by the eye muscles).
Auricle, in human anatomy, the visible portion of the external ear, and the point of difference between the human ear and that of other mammals. The auricle in humans is almost rudimentary and generally immobile and lies close to the side of the head. It is composed of a thin plate of yellow
Inner ear, part of the ear that contains organs of the senses of hearing and equilibrium. The bony labyrinth, a cavity in the temporal bone, is divided into three sections: the vestibule, the semicircular canals, and the cochlea. Within the bony labyrinth is a membranous labyrinth, which is also
When the alternating pressures of sound waves cause the eardrum to vibrate, the vibrations are transmitted along the columella and through the oval window to the inner ear, where they are relayed to the round window in a path across the otic capsule…
Human ear - Hearing, Anatomy, Physiology: Hearing is the process by which the ear transforms sound vibrations in the external environment into nerve impulses that are conveyed to the brain, where they are interpreted as sounds.
anatomy, a field in the biological sciences concerned with the identification and description of the body structures of living things. Gross anatomy involves the study of major body structures by dissection and observation and in its narrowest sense is concerned only with the human body.
Human anatomy and physiology are treated in many different articles. For detailed discussions of specific tissues, organs, and systems, see human blood ; cardiovascular system ; human digestive system ; human endocrine system ; renal system ; skin ; human muscle system ; nervous system ; human reproductive system ; human respiration ; human ...
