  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 ...

    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 posterior extremities extend back to the level of the middle of the foramen magnum.

  4. Jugular tubercle - Wikipedia

    en.wikipedia.org/wiki/Jugular_tubercle

    The jugular tubercle (of occipital bone [1]) is a rounded prominence [2]: 568 /oval elevation [1] upon the superior (i.e. internal [1]) surface of the occipital condyle [2]: 817 at the junction of the basilar part and lateral part of the occipital bone, just medial to the jugular foramen [2]: 568 [1] on either side of the foramen magnum.

  5. Occipital bone - Wikipedia

    en.wikipedia.org/wiki/Occipital_bone

    The occipital bone overlies the occipital lobes of the cerebrum. At the base of the skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the passage of the spinal cord. Like the other cranial bones, it is classed as a flat bone. Due to its many attachments and features, the occipital bone is ...

  6. Neurocranium - Wikipedia

    en.wikipedia.org/wiki/Neurocranium

    1 occipital bone; 2 parietal bones; 1 sphenoid bone; 2 temporal bones; The ossicles (three on each side) are usually not included as bones of the neurocranium. [6] There may variably also be extra sutural bones present. Below the neurocranium is a complex of openings and bones, including the foramen magnum which houses the neural spine.

  7. Cavernous hemangioma - Wikipedia

    en.wikipedia.org/wiki/Cavernous_hemangioma

    Cavernous hemangiomas are erroneously called the most common benign tumors of the liver. [14] Usually one malformation exists, but multiple lesions can occur in the left or right lobe of the liver in 40% of patients. [3] Their sizes can range from a few millimeters to 20 centimetres. Those over 5 cm are often referred to as giant hemangiomas. [3]

  8. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    In a newborn, the junction of the parietal bones with the frontal and occipital bones, form the anterior (front) and posterior (back) fontanelle, or soft spots. The separation of the cranial bone plates at time of birth facilitate passage of the head of the fetus through the mother's birth canal, or pelvic girdle. The parietal bones, and ...

    The condylar canal (or condyloid canal) is a canal in the condyloid fossa of the lateral parts of occipital bone behind the occipital condyle.Resection of the rectus capitis posterior major and minor muscles reveals the bony recess leading to the condylar canal, which is situated posterior and lateral to the occipital condyle.
