Types of Bones in the Human Skeleton – Human Anatomy | Kenhub


Hello again, everyone! This is Matt from Kenhub,
and in this tutorial, we will explore the different types of bones found in the human
skeleton. There are five types that are generally recognized,
and they’re identified by their forms, either endochondral or membranous, and by their general
shape. They are the following: long, short, flat, sesamoid, and irregular. We’ll start with the long bones. They have
a more complex anatomy, so this will be the most challenging group to learn. Long bones
develop via endochondral ossification, a process in which the hyaline cartilage plate is slowly
replaced. A shaft or diaphysis connects the two ends
known each as the epiphysis. The marrow cavity is enclosed by the diaphysis which is thick,
compact bone. The epiphysis is mainly spongy bone and is covered by a thin layer of compact
bone. The articular ends participate in the joints. The metaphysis connects the diaphysis
and epiphysis at the neck of the bone and is the place of growth during development. This group of bones includes the humerus,
ulna, radius, fibula, tibia, femur, metacarpals, and phalanges. Next are the short bones which consist of
a thin external layer of compact bone, covering a vast spongy bone and marrow, making a shape
that is more or less cuboid. The carpal and tarsal bones fall into this category. In flat bones, two layers of compact bone
cover both spongy bone and bone marrow space. They grow by replacing connective tissue,
and fibrocartilage covers their articular surfaces. This group is compiled of the skull
bones, ribs, sternum, and the scapulae. A thin layer of compact bone covers a mass
of mostly spongy bone in our next group: the irregular bones. This group is not categorized
by shape but by bone content and includes bones of the skull, vertebrae, and hip. Sesamoid bones are found at the end of long
bones in the limbs where the tendons cross. For example, the patella bone in the knee.
They protect the tendons from excess wear by developing within the tendon and reducing
friction. This video is more fun than reading a textbook,

  1. interesting points ,if anyone else wants to discover anatomy and physiology course online try Corbandy Simple Physiology Crusher (do a search on google ) ? Ive heard some unbelievable things about it and my mate got great results with it

  2. Hello, I wished the bones could follow an order, for instance up and down, front and back it could go like: Long Bones: Humerus, ulna, radius, metacarpals, femur, trivia, fibular, phalanges. This way, it helps us memorize our bones in order as well. Thanks for taking it into consideration. Otherwise, great video with great information.

  3. We had tons of fun researching the topic and creating this video tutorial about the types of bones in the skeleton for you. Which one is your favourite bone and why? Let us know in the comments. Solidify your knowledge with our quiz about the bones of the skeletal system: https://khub.me/feogw Good luck and have fun!

  4. interesting points ,if anyone else is searching for anatomy of the human body 2 try Laophiaa Cranial Blueprint (do a google search ) ? Ive heard some pretty good things about it and my brother in law got cool success with it.
