endoskeleton;)
The skeletons of amphibians, like those of other vertebrates, are composed of bone and cartilage. They share a common structural organization, with a skull, vertebral column, and limb bones. Additionally, amphibian skeletons serve similar functions, providing support, protection, and facilitating movement. Despite some variations in specific adaptations, the fundamental similarities in skeletal structure reflect shared evolutionary ancestry among vertebrates.
The femur is the longest, strongest, and heaviest bone in the body.
The lower limb attaches at the hip region, where the femur (thigh bone) articulates with the pelvic bone to form the hip joint.
Arm bones of all mammals . APEX=A bird's wing bone
No. It's a limb with muscles and bones inside.
The humerus
The humerus is the largest and longest bone of the upper limb. It extends from the shoulder to the elbow and plays a key role in the function of the arm.
The procedure is most commonly performed for bone tumors and bone sarcomas,
The two main divisions are the Axial and Appendicular Skeletons.
The patellar ligament separates the kneecap from the lower limb. It connects the bottom of the kneecap to the tibia bone in the lower limb.
This is not true. All vertebrates do not posses five digits per limb. Actually, few don't even possess limbs, like most snakes(eg. cobra (Naja naja)).
A cast us used to stop you from moving the limb with the damaged bone in it. This assures that the bone heals straight and in the correct position.
