The structure of the human skeleton and the functions of each part

Osteomalacia Deficiency of vitamin D in adults causes osteomalacia. The frontal, parietal, and occipital bones of the cranium—along with the ribs and hip bones—are all examples of flat bones. These organs, the function of which involves motion, expansion, and contraction, must have a flexible and elastic protective covering.

Skeletal System Overview

It is not known whether or to what extent those differences are genetic or environmental. At other times, symptoms of joint pain can lead to diagnoses of other underlying health problems. The bones of the axial skeleton act as a hard shell to protect the internal organs—such as the brain and the heart —from damage caused by external forces.

Compact bone tissue forms the outer shell of bones. The patella or kneecap on each side is an example of a larger sesamoid bone. The human body is to some extent like a walking tower that moves on pillars, represented by the legs. There exist several general differences between the male and female skeletons.

Much of this substance is then replaced by bone during the second and third trimester, after the flesh such as muscle has formed around it; forming the skeleton.

The bones of ribs and cranium are thin, broad and curved. Thus, the motions of the body and its parts, all the way from the lunge of the football player to the delicate manipulations of a handicraft artist or of the use of complicated instruments by a scientist, are made possible by separate and individual engineering arrangements between muscle and bone.

Blood Cell Production Larger bones contain bone marrow, a spongy tissue inside the bones. The vast difference in height and limb length between birth and adulthood are mainly the result of endochondral ossification in the long bones.

A small band of hyaline cartilage remains in between the bones as a growth plate. The articular cartilage acts as a shock absorber and gliding surface between the bones to facilitate movement at the joint.

Diagram illustrating the general structure of long bones: Deep to the periosteum is the compact bone that makes up the hard, mineralized portion of the bone.

It is not as hard and rigid as bone but is stiffer and less flexible than muscle. Osteoarthritis can affect both the larger and smaller joints of the human skeleton.

Skeletal System

Calcium-rich foods include leafy green vegetables, broccoli, tofu, and fish such as salmon. The tarsals form joints with the five long metatarsals of the foot. Sesamoid bones grow to protect the tendon from stresses and strains at the joint and can help to give a mechanical advantage to muscles pulling on the tendon.

Chondroitin sulfate is a sugar made up primarily of oxygen and carbon. Finally, red bone marrow stores some iron in the form of the molecule ferritin and uses this iron to form hemoglobin in red blood cells. When medication is used, it may include bisphosphonatesStrontium ranelateand osteoporosis may be one factor considered when commencing Hormone replacement therapy.

Sexual dimorphism in the long bones is commonly characterized by morphometric or gross morphological analyses. Because they are thin, flat bones do not have a medullary cavity like the long bones.

Bones have a variety of shapes with a complex internal and external structure they are also lightweight, yet strong and hard. The sesamoid bones are formed after birth inside of tendons that run across joints.

Organs of Skeletal System and Their Functions

The pubis is located in the front part of the hip bone. It is a condition in which there is C or S shaped bending of vertebral spine and can be seen on the x-ray. Protecting internal organs from injury. The human skeleton, like that of other vertebratesconsists of two principal subdivisions, each with origins distinct from the others and each presenting certain individual features.

In many animals, the skeleton bones contain marrowwhich produces blood cells. The strong bones of the spine, pelvis and legs enable people to stand upright, supporting the weight of the entire body. Storage The skeletal system stores many different types of essential substances to facilitate growth and repair of the body.

When one considers the relation of these subdivisions of the skeleton to the soft parts of the human body—such as the nervous systemthe digestive systemthe respiratory systemthe cardiovascular systemand the voluntary muscles of the muscle system —it is clear that the functions of the skeleton are of three different types:The human body is everything that makes up, well, you.

The basic parts of the human body are the head, neck, torso, arms and legs. Our bodies consist of a number of biological systems that carry. Human skeleton organsare divided into two types, the appendicular skeleton and the axial skeleton.

The axial skeleton runs in the midline i.e. the axial plane of the body and is made up of a total of 80 bones. The skeleton is the body part that forms the supporting structure of an organism. There are several different skeletal types: the exoskeleton, which is the stable outer shell of an organism, the endoskeleton, which forms the support structure inside the body, the hydroskeleton, and the cytoskeleton.

This article is concerned primarily with the gross structure and the function of the skeleton of the normal human adult. The human skeleton, like that of other vertebrates, consists of two principal subdivisions, each with origins distinct from the others and each presenting certain individual features.

Functions of Human Life 5. Requirements for Human Life 6. Homeostasis List and describe the functions of the skeletal system; Bone, or osseous tissue, is a hard, dense connective tissue that forms most of the adult skeleton, the support structure of the body.

In the areas of the skeleton where bones move (for example. The human skeletal system consists of all of the bones, cartilage, tendons, and ligaments in the body.

Altogether, the skeleton makes up about 20 percent of a person’s body weight. An adult’s.
