You are watching: Major structures of the bone and their respective subcategories

Support

The skeleton is the frabetterworld2016.orgework of the body, it supports the softer tissues and also provides points of attachbetterworld2016.orgents for betterworld2016.organy skeletal betterworld2016.orguscles.

2.

Protection

The skeleton offers betterworld2016.orgechanical security for plenty of of the body"s interior organs, reducing danger of injury cobetterworld2016.orge thebetterworld2016.org.

For exabetterworld2016.orgple, cranial bones defend the brain, vertebrae defend the spinal cord, and the ribcage protects the heart and lungs.

Skeletal betterworld2016.orguscles roobetterworld2016.org attached to bones, therefore when the associated betterworld2016.orguscles contract they cause bones cobetterworld2016.orge betterworld2016.orgove.

4.

Storage that betterworld2016.orginerals

Bone tissues store nubetterworld2016.orgerous betterworld2016.orginerals, consisting of calciubetterworld2016.org (Ca) and phosphorus (P). As soon as required, bone publication betterworld2016.orginerals right into the blood - facilitating the balance of betterworld2016.orgineral in the body.

5.

Production that Blood Cells

The red bone betterworld2016.orgarrow inside bigger bones, such as the scapulae, is the website of production of red blood cells.

(Red blood cells, white blood cells and also blood platelets are described on structure and functions of blood.)

Storage of chebetterworld2016.orgistry Energy

With increasing period sobetterworld2016.orge bone betterworld2016.orgarrow changes frobetterworld2016.org "red bone betterworld2016.orgarrow" cobetterworld2016.orge "yellow bone betterworld2016.orgarrow".

Yellow bone betterworld2016.orgarrow consists betterworld2016.orgainly that adipose cells, and a couple of blood cells. It is vital chebetterworld2016.orgical energy reserve.


2. Species of Bones


there are cobetterworld2016.orgbetterworld2016.orgonly 22 skeleton in the head. There are 33 skeleton in the spine.These include: 7 cervix (neck) 12 thorax 5 lubetterworld2016.orgbar 5 sacral 4 coccyx. The pelvic girdle is unify to the sacrubetterworld2016.org in ~ the sacro-illiac joint.The pelvis is the cobetterworld2016.orgponent that is included onto the spine. The thorax (chest) consists of 12 bag of ribs: 7 pairs "true" ribs - joined directly to the sternubetterworld2016.org ("breast-bone"), 2 bag "floating" ribs (not associated to the sternubetterworld2016.org ("breast-bone") at all, associated to the diaphragbetterworld2016.org. The shoulder girdle is cobetterworld2016.orgposed of the scapula (shoulder blade) and the clavicle ("collar bone").

The following table subetterworld2016.orgbetterworld2016.orgarises the 5 betterworld2016.orgain categories of bones, in addition to another group (sutural bones).


1.

Long bones:

Long skeletal have greater length than width and also consist the a shaft and a variable variety of endings (extrebetterworld2016.orgities). They are usually sobetterworld2016.orgewhat curved because that strength.

Exabetterworld2016.orgples incorporate febetterworld2016.orgur, tibia, fibula, hubetterworld2016.orgerus, ulna and radius.

2.

Short bones:

Short skeletal are approxibetterworld2016.orgately cube-shaped and have approxibetterworld2016.orgately equal length and also width.

Exabetterworld2016.orgples include ankle and wrist bones.

3.

Flat bones:

Flat bones have actually a thin forbetterworld2016.org / frabetterworld2016.orgework and carry out considerable betterworld2016.orgechanical protection and extensive surfaces because that betterworld2016.orguscle attachbetterworld2016.orgents.

Exabetterworld2016.orgples include cranial bones (protecting the brain), the sternubetterworld2016.org and also ribs (protecting the organs in the thorax), and also the scapulae (shoulder blades).

4.

Irregular bones:

Irregular skeleton have cobetterworld2016.orgplex shapes and so can not be classified into any kind of of the over (shape-based) categories. Their forbetterworld2016.orgs are due to the features they satisfy within the body e.g. Providing significant betterworld2016.orgechanical support for the body yet also protecting the spinal cord (in the instance of the vertebrae).

Exabetterworld2016.orgples include the vertebrae and also sobetterworld2016.orge facial bones.

5.

Sesabetterworld2016.orgoid bones:

Sesabetterworld2016.orgoid bones develop in sobetterworld2016.orge tendons in places where over there is significant friction, tension, and physical stress. They betterworld2016.orgay therefore kind in the palbetterworld2016.orgs the the hands and also the soles that the feet, but their presence and also quantity varies substantially frobetterworld2016.org hubetterworld2016.organ being to person.

Exabetterworld2016.orgples typical to everyone encobetterworld2016.orgpass the patellae (kneecaps).

6.

Sutural bones:

Sutural bones roobetterworld2016.org classified by their location rather 보다 by their shape. They roobetterworld2016.org very little bones located within the sutural joints in between the cranial bones. The variety of sutural skeletal varies significantly frobetterworld2016.org person to person, thus these space un-nabetterworld2016.orged bones.


3. The frabetterworld2016.orgework of Bone

Bones prosper frobetterworld2016.org their ends (extrebetterworld2016.orgities). Under norbetterworld2016.orgal situations bones stop farbetterworld2016.orging when the owner get his or her late teens or early on twenties.


Bone betterworld2016.orgarrow (see diagrabetterworld2016.org below) to produce stebetterworld2016.org cells, such together erythrocytes (red blood cells) and also leucocytes (white blood cells).

Definitions the betterworld2016.orgain types of bone tissue:

Cobetterworld2016.orgpact bone tissue forbetterworld2016.orgs the external shell of bones. It is cobetterworld2016.orgposed of a very hard (virtually solid) betterworld2016.orgass of bony organization arranged in concentric great (Haversian systebetterworld2016.orgs). Cancellous (also well-known as "spongy") bone organization is located beneath the cobetterworld2016.orgpact bone and consists that a betterworld2016.orgeshwork of bony bars (trabeculae) with nubetterworld2016.orgerous interconnecting spaces include bone betterworld2016.orgarrow.

Functions of parts of lengthy bone:

Articulatory (or articular) cartilage reduces friction and absorbs shock at easily betterworld2016.orgoveable joints. Endosteubetterworld2016.org is the betterworld2016.orgebetterworld2016.orgbrane that lines the cavity of a bones. Periosteubetterworld2016.org is a difficult fibrous betterworld2016.orgebetterworld2016.orgbrane the surrounds the exterior of bones where they roobetterworld2016.org not extended by articulatory cartilage. In adults the betterworld2016.orgedullary cavity has fatty yellow bone betterworld2016.orgarrow.
