Skeletal system

The skeletal system has several functions, among them the most outstanding are: Mechanical support of the body and its soft parts: functioning as a framework that maintains body morphology. Postural maintenance: allows postures such as standing.

Locomotor system

Types of bones

-Flat bones protect internalorgans. -Long bones support weight and facilitate movement. -Short bones are cube-shaped.

The cartilage

Cartilage is the firm but flexible tissue that covers the ends of bones in a joint. It also shapes and supports other parts of the body, such as the ears, nose, and windpipe. Healthy cartilage helps you move by allowing your bones to glide over each other.

The articulations

Joints are the joints between bones. They make the skeleton flexible; without them, movement would be impossible. Joints allow our body to move in many ways.Joints are distinguished into different types:de) Immobile joints or synarthrosis.b) Semi-mobile joints or amphiarthrosis.c) Mobile, synovial or diarthrosis joints.

The skeleton of an adult have 206 bones

the muscular system

The muscular system is a set of muscles that can be controlled voluntarily by a living organism (skeletal muscles). Its main function is to achieve mobility, an action that takes place when electrical stimuli from the nervous system cause the contraction of muscle fibers. .

Skeletal muscle is made up of muscle fibers, surrounded by a layer of connective tissue, called the endomysium. The fibers are gathered into primary fascicles, which are also surrounded by another layer of connective tissue, this time thicker, called the perimysium.

We have three types of muscles: smooth muscle, cardiac muscle, and skeletal muscle.

Muscle contraction is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them unite, and tension is produced in the area, thus achieving movement of either the skeletal muscle or the muscle. heart muscle.
