In other specimens, the mastoid artery is a branch of the occipital artery, rather than the auricular branch. Meningeal branch: supplies the dura mater in the posterior cranial fossa; Descending branches: This is the largest branch. It descends on the posterior aspect of the neck, and divides into a superficial and deep portion.
That area of the squamous part, which lies above the highest nuchal lines is named the occipital plane (planum occipitale) and is covered by the occipitalis muscle. That below, termed the nuchal plane , is rough and irregular for the attachment of several muscles.
The squamous part is the curved, expanded plate behind the foramen magnum and is the largest part of the occipital bone. Due to its embryonic derivation from paraxial mesoderm (as opposed to neural crest, from which many other craniofacial bones are derived), it has been posited that "the occipital bone as a whole could be considered as a giant ...
The occipital branches of occipital artery are terminal branches of the occipital artery which supply the back of the head. This page was last edited on 27 ...
Part of: Temporal bone of skull: System: Skeletal: Identifiers; ... a small branch of the occipital artery, the posterior meningeal artery, to the dura mater. [2 ...
The singular basioccipital is the rear lower part of the braincase, below the foramen magnum. It is homologous to the basilar part of the occipital bone. In the ancestral tetrapod, the basioccipital makes up most of a large central knob-like surface, the occipital condyle, which articulates with the vertebrae as a ball-and-socket joint. This ...
The internal surface [Fig. 2] is concave; it presents depressions corresponding to the cerebral convolutions, and numerous furrows (grooves) for the ramifications of the middle meningeal artery; the latter run upward and backward from the sphenoidal angle, and from the central and posterior part of the squamous border.
The temporal bone consists of four parts—the squamous, mastoid, petrous and tympanic parts. [1] [2] The squamous part is the largest and most superiorly positioned relative to the rest of the bone. The zygomatic process is a long, arched process projecting from the lower region of the squamous part and it articulates with the zygomatic bone ...
