hindlimb
Definition
Noun: A hindlimb is one of the paired posterior appendages of a quadruped (an animal with four limbs). It is a back limb, such as a leg, or the homologous anatomical structure in other animals.
Usage
The term is used primarily in biological and zoological contexts to describe the rear limbs of vertebrates, especially mammals, reptiles, and amphibians. * The powerful hindlimbs of a frog are adapted for jumping. * In the fossil, the structure of the hindlimb was clearly preserved. * The injury affected the animal's left hindlimb.
Advanced Usage
- In evolutionary biology, the term is used to discuss the homology (shared ancestry) of structures, such as comparing the hindlimb of a terrestrial mammal to the pelvic fin of a fish.
- The concept is often contrasted with forelimb (the front limb).
