Terminology, Taxonomy, and Domestication - Male rabbit: buck - Female rabbit: doe - Older term for adult rabbit: coney - Another term for young rabbit: bunny - Group of rabbits: colony or warren - Rabbits and hares were formerly classified as rodents - Rabbits belong to the order Lagomorpha - Lepus species are hares, not rabbits - Hares are generally larger than rabbits - Descendants of the European rabbit are commonly bred as livestock and pets - European rabbit has been widely domesticated since ancient Rome - Selective breeding has generated a wide variety of rabbit breeds - Some rabbit strains bred for research purposes - Rabbits bred for meat and fur - Rabbit fur comes in various colors and patterns

Biology and Evolution - Rabbits are obligate nasal breathers - Rabbits have two sets of incisor teeth - All rabbit teeth continue to grow - Rabbits have large hind leg bones and well-developed musculature - Rabbits use their claws for digging and defense - Rabbits share a common lineage with rodents - Recent DNA analysis supports their common ancestry - Rabbits and rodents are now grouped together in the superorder Glires - Rabbits have a field of vision of nearly 360 degrees - Rabbits have a more digitigrade posture while running

Hind limb structure and function - Hind limbs are longer than forelimbs, providing more force. - Rabbits run on their toes to optimize stride during locomotion. - Force from hind limbs is contributed by structural anatomy and muscles. - Fusion of tibia and fibula enhances force output. - Muscular features play a role in hind limb force generation.

Relationship between muscles and bone health - Bone formation and removal are influenced by hind limb muscles. - Muscle action pressure creates force distributed through skeletal structures. - Rabbits generating less force are more prone to osteoporosis. - Osteoporosis in rabbits is caused by bone rarefaction. - Hind limb muscles play a role in preventing bone rarefaction.

Impact of muscle fiber composition and role in acceleration - More muscle fibers in a muscle result in increased force generation. - Muscle fiber composition affects hind limb strength. - Fiber composition influences the force output of hind limb muscles. - Rabbits with more muscle fibers have greater hind limb power. - Hind limb muscles contribute to acceleration in rabbits. - Muscular force aids in rapid acceleration. - Acceleration is divided into foot, thigh, and leg movements. - Hind limb muscles generate the force necessary for acceleration. - Structural anatomy and muscle features support acceleration. - Hind limb structure is an exaggerated feature in rabbits. - Longer hind limbs provide increased force during locomotion. - Hind limb muscles are crucial for bone health and force generation. - Structural anatomy and muscular features work together for optimal performance. - Hind limb anatomy and muscles are key factors in rabbit locomotion.
