How many legs does a mouse have? - in detail
A mouse possesses four limbs. Each limb is a leg, anatomically classified as a forelimb or hindlimb. The forelimbs are positioned near the head and support activities such as climbing, digging, and manipulating objects. The hindlimbs are located toward the rear and provide propulsion for rapid movement and jumping.
Key anatomical features of the limbs include:
- Bone structure: Each leg contains the humerus (forelimb) or femur (hindlimb), followed by the radius and ulna or tibia and fibula, respectively, and ends in a series of small bones forming the wrist, ankle, and digits.
- Musculature: Muscles such as the biceps brachii and quadriceps femoris generate the force needed for grasping and locomotion.
- Digits: Five digits per limb, each ending in a claw that aids in traction and burrowing.
The quadrupedal arrangement enables efficient locomotion across varied terrains, from smooth surfaces to underground tunnels. This limb configuration is consistent across all species of mice, regardless of size or habitat.
