bones-
help us to walk and work
mucles-
changing posture and for motion
Answer:
Bones have many functions, including the following:
•Support: Bones provide a framework for the attachment of muscles and other tissues.
•Protection: Bones such as the skull and rib cage protect internal organs from injury.
•Movement: Bones enable body movements by acting as levers and points of attachment for muscles.
•Mineral storage: Bones serve as a reservoir for calcium and phosphorus, essential minerals for various cellular activities throughout the body.
•Blood cell production: The production of blood cells, or hematopoiesis, occurs in the red marrow found within the cavities of certain bones.
•Energy storage: Lipids, such as fats, stored in adipose cells of the yellow marrow serve as an energy reservoir.
FUNCTIONS OF MUSCLES ARE LISTED BELOW:
The main functions of the muscular system are as follows:
1. Mobility
The muscular system’s main function is to allow movement. When muscles contract, they contribute to gross and fine movement.
Gross movement refers to large, coordinated motions and includes:
walking
running
swimming
Fine movement involves smaller movements, such as:
writing
speaking
facial expressions
The smaller skeletal muscles are usually responsible for this type of action.
2. Stability
Muscle tendons stretch over joints and contribute to joint stability. Muscle tendons in the knee joint and the shoulder joint are crucial in stabilization.
3. Posture
Skeletal muscles help keep the body in the correct position when someone is sitting or standing. This is known as posture.
4. Circulation
The heart is a muscle that pumps blood throughout the body. The movement of the heart is outside of conscious control, and it contracts automatically when stimulated by electrical signals.
5. Respiration
Breathing involves the use of the diaphragm muscle.
The diaphragm is a dome-shaped muscle located below the lungs. When the diaphragm contracts, it pushes downward, causing the chest cavity to get bigger. The lungs then fill with air. When the diaphragm muscle relaxes, it pushes air out of the lungs.
6. Digestion
The muscular system allows for movement within the body, for example, during digestion or urination.
Smooth muscles in the gastrointestinal or GI tract control digestion. The GI tract stretches from the mouth to the anus.
7. Urination
The urinary system comprises both smooth and skeletal muscles, including those in the:
bladder
kidneys
penis or vagina
prostate
ureters
urethra
The muscles and nerves must work together to hold and release urine from the bladder.
8. Childbirth
Smooth muscles in the uterus expand and contract during childbirth. These movements push the baby through the vagina. Also, the pelvic floor muscles help to guide the baby’s head down the birth canal.
9. Vision
Six skeletal muscles around the eye control its movements. These muscles work quickly and precisely, and allow the eye to:
10. Organ protection
Muscles in the torso protect the internal organs at the front, sides, and back of the body. The bones of the spine and the ribs provide further protection.
11. Temperature regulation
Maintaining normal body temperature is an important function of the muscular system. Almost 85 percent of the heat a person generates in their body comes from contracting muscles.
