  2. Okapi - Wikipedia

    en.wikipedia.org/wiki/Okapi

    Male okapi displaying his striking horizontal stripes. The okapi is a medium-sized giraffid, standing 1.5 m (4 ft 11 in) tall at the shoulder. Its average body length is about 2.5 m (8 ft 2 in) and its weight ranges from 200 to 350 kg (440 to 770 lb). [23] It has a long neck, and large and flexible ears.

  3. Ossicone - Wikipedia

    en.wikipedia.org/wiki/Ossicone

    In okapi, the male's ossicones are smaller in proportion to the head, and taper towards their tips, forming a sharper point than the comparatively blunt giraffe ossicone. Whereas female giraffes have reduced ossicones, female okapi lack ossicones entirely. The morphology of ossicones in the extinct relatives of giraffes and okapi varies widely.

  4. Human head - Wikipedia

    en.wikipedia.org/wiki/Human_head

    Anatomy of the human head. The human head consists of a fleshy outer portion, which surrounds the bony skull. The brain is enclosed within the skull. There are 22 bones in the human head. The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between 2.3 and 5 kilograms (5.1 and 11.0 lb) Over 98 ...

  5. Paraceratherium - Wikipedia

    en.wikipedia.org/wiki/Paraceratherium

    The premolars only partially formed the pi pattern. Each molar was the size of a human fist; among mammals they were only exceeded in size by proboscideans, though they were small relative to the size of the skull. The lower cheek teeth were L-shaped, which is typical of rhinoceroses. [4]

  6. Mammal - Wikipedia

    en.wikipedia.org/wiki/Mammal

    A mammal (from Latin mamma 'breast') [1] is a vertebrate animal of the class Mammalia (/ m ə ˈ m eɪ l i. ə /).Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones.

  7. Crown (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Crown_(anatomy)

    The macroevolution of the human species resulted in changes such as the increase in bone and muscle structures that support the crown of the head, compared to primates. Modern human species have a cranial base which is more angled and a cranial vault that is rounded, compared to archaic human species.

  8. Tapir - Wikipedia

    en.wikipedia.org/wiki/Tapir

    The evolution of tapir probosces, made up almost entirely of soft tissues rather than bony internal structures, gives the Tapiridae skull a unique form in comparison to other perissodactyls, with a larger sagittal crest, orbits positioned more rostrally, a posteriorly telescoped cranium, and a more elongated and retracted nasoincisive incisure.

  9. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    The head rests on the top part of the vertebral column, with the skull joining at C1 (the first cervical vertebra known as the atlas).The skeletal section of the head and neck forms the top part of the axial skeleton and is made up of the skull, hyoid bone, auditory ossicles, and cervical spine.
