The styloid process is a slender and pointed bony process of the temporal bone projecting anteroinferiorly from the inferior surface of the temporal bone [1] just below the ear. [citation needed] Its length normally ranges from just under 3 cm to just over 4 cm. It is usually nearly straight, but may be curved in some individuals. [1]
Two parts of the hyoid arch: the styloid process. In the dog the styloid process is represented by a series of four articulating bones, from top down tympanohyal, stylohyal, epihyal, ceratohyal; the first two represent the styloid process, and the ceratohyal represents the anterior horns of the hyoid bone and articulates with the basihyal which ...
The body of the hyoid bone is the central part of the hyoid bone. [clarification needed]At the front, the body is convex and directed forward and upward. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.
Its originates from the styloid process of the temporal bone; it inserts onto hyoid bone. It is innervated by a branch of the facial nerve . It acts draw the hyoid bone upwards and backwards.
It attaches at the lesser horn of the hyoid bone [1] [2] inferiorly, [citation needed] and (the apex of [1]) the styloid process of the temporal bone [1] [2] superiorly. [citation needed] The ligament gives attachment to the superior-most fibres of the middle pharyngeal constrictor muscle. [1]
Caudal to what will eventually become the stapes, Reichert's cartilage also forms the styloid process of the temporal bone. The cartilage between the hyoid bone and styloid process will not remain as development continues, but its perichondrium will eventually form the stylohyoid ligament.
In anatomy, a styloid process (from Greek stylos (στῦλος), "pillar"), usually serving as points of attachment for muscles, refers to the slender, pointed process (protrusion) of: temporal bone of the skull - Temporal styloid process; radius bone of the lower arm - Radial styloid process; ulna bone of the lower arm - Ulnar styloid process
extending backward from the carotid canal is the vaginal process, a sheath-like plate of bone, which divides behind into two laminæ; the lateral lamina is continuous with the tympanic part of the bone, the medial with the lateral margin of the jugular surface; between these laminæ is the styloid process, a sharp spine, about 2.5 cm. in length
