This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
Its lateral edge corresponds with the remains of the petrosquamous suture. [1] The Atticus is the part of the tegmentum tympani where the stapes and incus are attached. The floor of the cavity (also called the jugular wall) is narrow, and consists of a thin plate of bone (fundus tympani) which separates the tympanic cavity from the jugular ...
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
A sinus is a sac or cavity in any organ or tissue, or an abnormal cavity or passage. In common usage, "sinus" usually refers to the paranasal sinuses, which are air cavities in the cranial bones, especially those near the nose and connecting to it. Most individuals have four paired cavities located in the cranial bone or skull.
[1] [2] The proximal opening of the canal is situated upon the inferior surface of the petrous part of the temporal bone; its distal opening is situated upon the floor of the tympanic cavity. [1] The canal gives passage to the tympanic nerve (tympanic branch of the glossopharyngeal nerve) (CN IX)) and inferior tympanic artery [3] [2]
The following terms are used to describe the walls of a cavity: A labyrinth refers to the bony labyrinth and membranous labyrinth, components of the inner ear, due to their fine and complex structure. [17] A sinus refers to a bony cavity, usually within the skull. [18]
The proximal opening of the canal occurs near the mid-point of the infraorbital canal. [ 1 ] : 616 From its proximal opening, the canalis sinuosus first passes infero [ 1 ] : 616 laterally [ 1 ] : 653–654 within the maxillary orbital floor where it is situated lateral to the infraorbital canal.
