musculoskeletal system
The skeIetaI system
skeIetaI system is aII the bones in the body, Iike,
Iigaments,cartiIage and joints it has 5 major function, which are:
1.Protection, movement and support
Since they are connected to the muscles, bones enable the body to move. Bones
serve as a foundation for muscles; without them, muscles will be unable to
contract and move. Bones also shield body organs from injury; they act as an
inner shieId for our bodies.
2.storage and creating bIood ceIIs
bones store minerals like calcium and phosphorus and afterward
discharge them into the circulation system. CaIcium, for instance, is
required for muscle withdrawal just as nerve motivation transmission,
fat stockpiling, and platelet arrangement in the bone marrow. The two
sorts of bone marrow are red bone marrow and yellow bone marrow.
The red bone marrow is liable for blood ceII handling just as the
improvement of white blood ceIIs and pIateIets, while the yellow
bone marrow is liable for fat preparing
bones.
a bone is a hard tissue that is a piece of the vertebrate skeleton. Bones
secure the body's inside organs, make platelets, store minerals, give the
body solidness and backing, they likewise fill in as connection base for
muscles to permit portability. Bones have a complex inside and outer
design that arrives in a scope of shapes and sizes.
Type of bones:
1. FIat bones:
,They protect the inside organs of the body and support the muscIes
to attach to them
ExampIes of fIat bones are ; ribs, sternum,ischium. Pubis.
2. Iong bones:
They support the body weight and allow mobility they are moslty
located in the appendicuIar skeIeton
ExampIes of Iong bones ; the phaIanges, metacarpaIs
3. Short bones
Short bones are about a similar width as they are tall, and their
main role is to give equilibrium and dependability negligible
development.
Examples of short bones ; Carpals and Tarsals
4. IrreguIar bones:
The irregular bones are those that, due to their unusual shape,
cannot be classified as long, short, flat, or sesamoid.
Irregular bones perform a variety of functions in the body,
including protecting nervous tissue, providing several anchor
points for skeletal muscle attachment, and supporting the
pharynx and trachea.
ExampIes; vertebrae. the irreguIar bones of the vertebraI coIumn
5. Sesamoid bones:
sesamoid bone are small bones that are located within a tendon or a
muscle. These bones can develop as a result of strain or as a
natural variation.
The kneecap is the body's largest sesamoid bone.
Sesamoids act as pulleys, they give a smooth surface for tendons to
slide on

Iigaments and tendons :
Joints are when two or more bones meet to allow movement
Iigaments are rigid elastic bands that wrap around the joints,
connecting bones to bones, supporting them, and restricting their
movement.
Iigaments are Iocated in the knee and ankIes, shouIders, eIbows
etc..
A tendon is a strong band of connective tissue which connects
muscles to bones.
Tendons and ligaments are both collagen-based structures.

The muscuIar system:
Muscles give us the ability to move our bodies. They also serve to protect and protect
the internal organs. Muscles are about 40% of the total body weight. Muscles are
designed in the same way as elastic tissue is. Thousands of tiny muscuIus fibres make
up each muscle.Those muscIe fibres are made up of tiny fibriI threads.When muscIe
fibres contract, the whoIe muscIe contracts, supporting organ functions and allowing us
to move if it isa voluntary muscIe. Muscles require energy to contract, which is obtained
when the human body breaks down food into adenosine triphosphate
