Posterior Ligament Of The Incus
The posterior ligament of the incus is a fibrous band that connects the tip of the short crus of the incus to the fossa incudis, running to the mastoid (posterior wall of the middle ear chamber). The posterior incudal ligament plays an important role in the vibration of the middle ear bones: together with the anterior ligament of the malleus The ligaments of malleus are three ligaments that attach the malleus in the middle ear. They are the anterior, lateral and superior ligaments. The anterior ligament of the malleus also known as Casserio's ligament is a fibrous band that exten ..., it forms a pivotal axis around which the ossicles rotate. This rotation conveys vibrations from the tympanum to the oval window on the bony labyrinth (where they can be transduced into electrical signals transmitted to the nervous system).

Incus
The ''incus'' (: incudes) or anvil in the ear is one of three small bones (ossicles) in the middle ear. The incus receives vibrations from the malleus, to which it is connected laterally, and transmits these to the stapes medially. The incus is named for its resemblance to an anvil (). Structure The incus is the second of three ossicles, very small bones in the middle ear which act to transmit sound. It is shaped like an anvil, and has a long and short crus extending from the body, which articulates with the malleus. The short crus attaches to the posterior ligament of the incus. The long crus articulates with the stapes at the lenticular process. The superior ligament of the incus attaches at the body of the incus to the roof of the tympanic cavity. The incus is Homology (biology), homologous to the quadrate bone found in other tetrapods. Function Vibrations in the middle ear are received via the tympanic membrane. The malleus, resting on the membrane, conveys vibrations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossa (anatomy)
In anatomy, a fossa (; : fossae ( or ); ) is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone).Venieratos D, Anagnostopoulou S, Garidou A., A new morphometric method for the sella turcica and the hypophyseal fossa and its clinical relevance.;Folia Morphol (Warsz). 2005 Nov;64(4):240-7. Some examples include: In the skull: * Cranial fossa ** Anterior cranial fossa ** Middle cranial fossa *** Interpeduncular fossa ** Posterior cranial fossa * Hypophyseal fossa * Temporal bone fossa ** Mandibular fossa ** Jugular fossa * Infratemporal fossa * Pterygopalatine fossa * Pterygoid fossa * Lacrimal fossa ** Fossa for lacrimal gland ** Fossa for lacrimal sac * Scaphoid fossa * Condyloid fossa * Rhomboid fossa In the mandible: * Retromolar fossa In the torso: * Fossa ovalis (heart) * Infraclavicular fossa * Pyriform fossa * Substernal fossa * Iliac fossa * Ovarian fossa * Paravesical fossa * Coccygeal f ...

Anterior Ligament Of The Malleus
The ligaments of malleus are three ligaments that attach the malleus in the middle ear. They are the anterior, lateral and superior ligaments. The anterior ligament of the malleus also known as Casserio's ligament is a fibrous band that extends from the neck of the malleus just above its anterior process to the anterior wall of the tympanic cavity close to the petrotympanic fissure. Some of the fibers also pass through the fissure to the spine of sphenoid bone. The lateral ligament of the malleus is a triangular fibrous band that crosses from the posterior aspect of the tympanic notch to the head or neck of the malleus. The superior ligament of the malleus is a delicate fibrous strand that crosses from the roof of the tympanic cavity The tympanic cavity is a small cavity surrounding the bones of the middle ear. Within it sit the ossicles, three small bones that transmit vibrations used in the detection of sound. Structure On its lateral surface, it abuts the extern ...

Human Head And Neck
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's deve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
