  2. Occipital condyles - Wikipedia

    en.wikipedia.org/wiki/Occipital_condyles

    The occipital condyles are undersurface protuberances of the occipital bone in vertebrates, which function in articulation with the superior facets of the atlas vertebra.. The condyles are oval or reniform (kidney-shaped) in shape, and their anterior extremities, directed forward and medialward, are closer together than their posterior, and encroach on the basilar portion of the bone; the ...

  3. Basilar part of occipital bone - Wikipedia

    en.wikipedia.org/wiki/Basilar_part_of_occipital_bone

    The basilar part of the occipital bone (also basioccipital) extends forward and upward from the foramen magnum, and presents in front an area more or less quadrilateral in outline. In the young skull, this area is rough and uneven, and is joined to the body of the sphenoid by a plate of cartilage.

  4. Neurocranium - Wikipedia

    en.wikipedia.org/wiki/Neurocranium

    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 .

  5. Occipital bone - Wikipedia

    en.wikipedia.org/wiki/Occipital_bone

    Due to its many attachments and features, the occipital bone is described in terms of separate parts. From its front to the back is the basilar part, also called the basioccipital, at the sides of the foramen magnum are the lateral parts, also called the exoccipitals, and the back is named as the squamous part.

  6. Lateral parts of occipital bone - Wikipedia

    en.wikipedia.org/wiki/Lateral_parts_of_occipital...

    The under surface of the jugular process is rough, and gives attachment to the Rectus capitis lateralis muscle and the lateral atlanto-occipital ligament; from this surface an eminence, the paramastoid process, sometimes projects downward, and may be of sufficient length to reach, and articulate with, the transverse process of the atlas.

  7. Suboccipital muscles - Wikipedia

    en.wikipedia.org/wiki/Suboccipital_muscles

    The suboccipital muscles are a group of muscles defined by their location to the occiput. Suboccipital muscles are located below the occipital bone. These are four paired muscles on the underside of the occipital bone; the two straight muscles (rectus) and the two oblique muscles (obliquus). The muscles are named

    To it is attached, the splenius capitis muscle, the trapezius muscle, [1] and the occipitalis. [ 2 ] From the external occipital protuberance a ridge or crest, the external occipital crest also called the median nuchal line , often faintly marked, descends to the foramen magnum , and affords attachment to the nuchal ligament .

  9. List of skeletal muscles of the human body - Wikipedia

    The location of the muscle in a standard human body. The location first specifies a group such as head, neck, torso, upper limbs, or lower limbs, then may have more specific information. However this additional information must be describing location not function. Origin The bone or other structure the muscle is attached to that remains ...
