The humerus is the bone in the upper arm.
The radius and the ulna are the bones in the forearm.
The femur is the bone in the thigh.
The tibia and the fibula are the bones in the lower leg.
It has organs belonging to the muscular system, the skeletal system, the cardiovascular system, the integumentary system and the nervous system in it. Muscles, bones, blood vessels, nerves and skin.
The humerus is the bone in the upper arm that connects the shoulder to the elbow. It is the largest bone in the arm and plays a crucial role in arm movement and strength.
Skeletal system
Skeletal system
The radius belongs to the skeletal system. It is the lateral bone in the forearm.
The axial skeleton.
The muscles are connected to the bones. Without the bones, the muscles would fall down in a mass of mush, but without the muscles, the bones would not be able to make our bodies move. We would always stay still.
Skeletal system: The bones of the arm need to be correctly aligned and secured during reattachment surgery. Muscular system: Muscles and tendons in the arm need to be carefully reattached to ensure proper function. Circulatory system: Blood vessels must be reconnected to restore blood flow to the arm. Nervous system: Nerves in the arm must be repaired to restore sensation and movement. Integumentary system: The skin and other tissues need to be stitched back together to promote healing and prevent infection.
The skeletal elements of the proximal segment of the upper limb include the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone). These bones form the shoulder girdle and provide attachments for muscles that enable arm movements.
Skeletal muscles in the arm
Muscles are attaches to tendons, which in turn are attached to bones. So if you wanted to bend your arm, the biceps pulls on the tendon which is attached to the Radius and Ulna.
The skeletal system is closely related to the muscular system. When you think on walking, or making any other movement, the muscular system that makes part of the bones, articulations, tendons, gets an order from the brain, thus actuating the limbs that make you stand up, walk, rise your arm,and so on.
