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.
