Osseous tissue

A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions.

Soft tissue

Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bones and teeth. Soft tissue connects, surrounds or supports internal organs and bones, and includes muscle, tendons, ligaments, fat, fibrous tissue, lymph and blood vessels, fasciae, and synovial membranes.

Bone marrow

骨髓(拉丁语:Medulla ossium;英语:Bone marrow)是一种位于较大骨骼腔中的半固态组织,主要由造血组织、脂肪组织与支持造血干细胞分化的骨髓间质组成。对人体而言,产后造血能力主要由骨髓支撑。骨髓约占人体体重的4-6%,主要分布于肋骨、椎骨、胸骨,以及骨盆中。

成人体内的骨髓每天大约能产生1000亿个血细胞,产生的血细胞通过骨髓中的血窦进入血液循环。通常人体在稳定状况下,每小时约有1010个红细胞与108-109个白细胞生成,以维持外周血循环中血细胞的组成与数量。在骨髓产生的血细胞中,髓系细胞(红细胞系、粒细胞系、单核细胞系与巨核细胞-血小板系)是完全在骨髓内分化生成的;淋巴系细胞(T细胞与B细胞)的发育前期是在骨髓内完成;另外B细胞分化为浆细胞后,也回到骨髓,并在这里大量产生抗体。

  • 胼pan胝zhi体
  • The corpus callosum is found only in placental mammals, while it is absent in monotremes and marsupials, as well as other vertebrates such as birds, reptiles, amphibians and fish.
