Why is the long bone important in body?
Long bones play several crucial roles in the body. Here are some of their importance:
Structural support: Long bones are predominantly responsible for providing structural support and stability to the body. They form the framework of the limbs and help maintain the body's overall shape.
Skeletal system: Long bones are an integral part of the skeletal system, which provides a strong and rigid framework for the body. They protect vital organs, muscles, and tissues from external impacts and injuries.
Mobility: Long bones enable mobility and facilitate movement. They serve as levers that allow muscles to attach and exert force, enabling various types of joint movements like flexion, extension, rotation, and abduction.
Bone marrow production: The marrow cavity within long bones produces red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). Red blood cells carry oxygen to tissues, white blood cells fight infections, and platelets help with blood clotting.
Mineral storage: Long bones serve as reservoirs for minerals such as calcium and phosphorus. These minerals contribute to bone strength and hardness. When the body needs these minerals for other processes, they can be released and utilized from bone stores.
Weight bearing: Long bones, particularly those in the legs, bear the weight of the body. They withstand the forces exerted during activities such as walking, running, and jumping. This weight-bearing capability is essential for daily physical activities and mobility.
Muscle attachment: Long bones provide attachment points for numerous muscles. Muscles connect to specific areas on long bones, allowing them to exert forces and generate movements.
Protection: Long bones help protect vital organs, tissues, and blood vessels within the limbs. They shield these structures from external impacts and trauma, reducing the risk of damage or injuries.
Growth and development: Long bones play a crucial role in growth and development during childhood and adolescence. Their growth plates allow for lengthening of the bones, contributing to the overall physical growth of the individual.
Shock absorption: Long bones, particularly those in the legs, contribute to shock absorption during activities like walking and running. They provide cushioning and help reduce impact forces on joints and muscles.
