Bone Basics and Bone Anatomy Each bone in your body is made up of three main types of bone material: compact bone, spongy bone, and bone marrow. Compact bone. Compact bone is the heaviest, hardest type of bone. It needs to be very strong as it supports your body and muscles as you walk, run, and move throughout the day.how/hide words to know. 1  Bone marrow: the tissue in the middle of bones that creates red and white blood cells 2  ...

Types of Bones  (Bone Types) They consist of a shaft - which is the main (long) part and variable number of endings (extremities), depending on the joints formed at one or both ends of the long bone. Long bones are usually somewhat curved - contributing to their mechanical strength. 1  Femur (leg bone) 2  Tibia (leg bone)  Fibula (leg bone)

SECTION ONE STRUCTURE AND FUNCTION OF BONE The three major components of bone are osteogenic cells, organic matrix, and mineral. The osteogenic cells include osteoblasts, osteocytes, and osteoclasts, while the matrix consists predominantly of collagen and proteoglycans and constitutes approximately one third of the bone mass.one tissue is the structural material that gives the bones the strength they require to act as levers for muscles, to give form to the soft tissues of the body, and to provide protective cavities for the vital organs.

The Femur The femur is the only bone in the thigh. It is classed as a long bone, and is in fact the longest bone in the body. The main function of the femur is to transmit forces from the tibia to the hip joint. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three areas; proximal, shaft and distal.

Sphenoid Bone Sphenoid bone - internal view There are four main parts to the sphenoid bone: the body (corpus), the lesser and greater wings (alae minores et majores) and the pterygoid processes. The body is the most centrally positioned portion. Anteriorly it contributes to the nasal cavity, laterally it builds the medial wall of the optic canal.

- The 206 named bones of the human skeleton are divided into two groups: axial and appendicular. The axial skeleton forms the long axis of the body and includes the bones of the skull, vertebral column, and rib cage. The fused bones of the skull protect the brain. 2  The vertebrae surround the spinal cord, and the rib cage helps protect the vital organs of the thorax. 3  Movement. 4  Skeletal muscles, which attach to bones by tendons, use bones as levers to move the body and its parts.

Skeletal System and Bone Function Bones of the skeletal system can be classified into four major types. They are categorized by shape and size. The four main bone classifications are long, short, flat and irregular bones. Long bones are bones that have greater length than width. Examples include arm, leg, finger, and thigh bones.

- About Growth Plates. All long bones have an area called the epiphysis, which is the rounded end of the bone. The long, middle part (or shaft) of the bone is the diaphysis; the area where the bone gets wider at its end is the metaphysis. In growing kids, growth plates sit between the metaphysis and the epiphysis.

Types of Bones  (Bone Types) Types of Bones or  Bone Types  can be classified according to the shape of the bone. The shape of bones reflect their functions. When describing specific bones it can be useful to start by stating the type of bone in terms of its shape, e.g.  the scapula is a large flat triangular bone .The main 5 types of bone (in terms of bone shape) are listed in the following table together with brief descriptions and examples of each.First remember the list of types of bones: 1  Long Bones.2  Short Bones. 3  Flat Bones.4  Irregular Bones..g.  the scapula is a large flat triangular bone .

What are the different parts of the foot? A Dr. Christopher Chiodo, MD, Orthopedic Surgery, answered. Your foot consists of three main components: the forefoot (the toes and ball of your foot), the midfoot (the arch), and the hindfoot (the heel region).The underlying bone structure is intricate and complex.ive longer bones, known collectively as the metatarsals, lead to the toes. Hidden under the base of the big toe are bones called sesamoids, which work like pulleys, enhancing the function of muscles and tendons and increasing the strength of the big toe.

- A bone is a rigid organ that constitutes part of the vertebral skeleton. Bones support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. protrusion from a bone can be called a number of terms, including a condyle, crest, spine, eminence, tubercle or tuberosity, depending on the protrusion's shape and location. In general, long bones are said to have a head, neck, and body.

- Structure of a Typical Long Bone Long bones have a tubular bone shaft, consisting of a bone collar surrounding a hollow medullary cavity, which is filled with yellow bone marrow in adults. Epiphyses are at the ends of the bone, and consist of internal spongy bone covered by an outer layer of compact bone.The epiphyseal line is located between the epiphyses and diaphysis, and is a remnant of the epiphyseal plate. The external surface of the bone is covered by the periosteum.piphyses are at the ends of the bone, and consist of internal spongy bone covered by an outer layer of compact bone.

Human skeleton The axial skeleton is formed by the vertebral column, the rib cage, the skull and other associated bones. The appendicular skeleton, which is attached to the axial skeleton, is formed by the shoulder girdle, the pelvic girdle and the bones of the upper and lower limbs. The human skeleton performs six major functions; support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation.

Types of Bones Types of Bones. There are four major types of bones. They are: long bones, short bones, flat bones, and irregular bones. The primary differences between the bones are their shape, and material they are made of. The four types are listed below, in more detail, along with a diagram of each showing the primary differences. Long Bones.

The Structure and Functions of Bones Types of Bones. 1  There are axial and appendicular bones. (The appendages are the arms and legs, which contain approx. 30 bones each.) 2  There are typically 22 bones in the head. 3  There are 33 bones in the spine. These include: 7 cervix (neck) 12 thorax. 4  The pelvic girdle is fused to the sacrum at the sacro-illiac joint.

Long bone The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility.he long bones include the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones. The long bones of the human leg comprise nearly half of adult height.

Which is the strongest bone in the body? The three long bones are your femur, your tibia and your fibula. The fourth bone is your small patella, which is better known as the kneecap. Your femur, or thighbone, is the largest bone in your body. The head of your femur fits into your hip socket and the bottom end connects to your knee.The two bones beneath your knee that make up your shin are your tibia and fibula. Your upper and lower leg are connected by a hinge joint.he three long bones are your femur, your tibia and your fibula. The fourth bone is your small patella, which is better known as the kneecap.

What are the main functions of the skeletal system? Our bones are held together by strong elastic-like bands called ligaments. Our skeleton is very important to us. It has three main functions: 1. It protects the important organs inside our body such as the brain, the heart and the lungs. The bony part of the head is called skull. The bones around our chest form a rib cage. 2. The skeleton supports our body and gives it shape. It is like a container for all the internal organs and tissues of the body.
