Skeleton of the rabbit. Since speed and agility are a rabbit's main defenses against predators, rabbits have large hind leg bones and well-developed musculature. Though plantigrade at rest, rabbits are on their toes while running, assuming a more digitigrade posture. [51]
Ribbon diagram of an actin monomer from rabbit skeletal muscle, with the molecule's surface shown semi-transparent. The four subdomains as well as the bound ATP and calcium ion are annotated. The four subdomains as well as the bound ATP and calcium ion are annotated.
Skeleton of Alaskan Hare on display at the Museum of Osteology. Leporidae (/ l ə ˈ p ɔː r ɪ d iː,-d aɪ /) is the family of rabbits and hares, containing over 70 species of extant mammals in all. The Latin word Leporidae means "those that resemble lepus" (hare). Together with the pikas, the Leporidae constitute the mammalian order ...
Oryctolagus (/ ˌ ɔː r ɪ k ˈ t ɑː l ə ɡ ə s /) is a genus of lagomorph that today contains the European rabbit and its descendant, the domestic rabbit, as well as several fossil species. The generic name derives from Ancient Greek: ὀρυκτός (oryktos, “dug up”) and λαγώς (lagōs, “hare”). [1]
Rabbits and hares move by jumping, pushing off with their strong hind legs and using their forelimbs to soften the impact on landing. Pikas lack certain skeletal modifications present in leporids, such as a highly arched skull, an upright posture of the head, strong hind limbs and pelvic girdle, and long limbs. [19]
Skeletal muscle myosin, the most conspicuous of the myosin superfamily due to its abundance in muscle fibers, was the first to be discovered. This protein makes up part of the sarcomere and forms macromolecular filaments composed of multiple myosin subunits.
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
Size of Nuralagus compared with a European rabbit and a person 5'9" tall. A Nuralagus femur compared to a European rabbit femur.. With a height of half a meter and an estimated weight of 12 kg (26 lb), [1] [2] or 8 kg (18 lb) [3] the species is the largest known lagomorph, being ten times the weight of the average wild European rabbit (Oryctolagus cuniculus) and around double the weight of the ...
