Name: The Skeleton, Joints and Disorders
Author: StemPy Lab

How the 206 bones of the human skeleton are grouped, and which belong to the axial and which to the appendicular skeleton. The skull, the spine and the ribs, then the girdles and the limbs. The types of joint, and the disorders of muscles and bones such as myasthenia gravis, tetany, arthritis, osteoporosis and gout. It covers the unit of the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP.

Lesson 1about 30 min
Bone, cartilage and the axial skeleton
The human skeleton is a framework of 206 bones and a few cartilages. It has an axial part of 80 bones, which holds the skull, the vertebral column, the sternum and the ribs, and an appendicular part with the limbs and the girdles. This lesson counts the bones of the axial skeleton, part by part, and says what each part protects.

Lesson 2about 25 min
The girdles and the limbs
The appendicular skeleton holds the bones of the limbs and of the two girdles. Each limb has 30 bones. The pectoral girdle joins the fore limbs to the axis, and the pelvic girdle joins the hind limbs. Together they make 126 bones, and with the 80 of the axial skeleton they make the 206 bones of the whole skeleton.

Lesson 3about 25 min
Joints and the disorders of muscles and bones
A joint is a point of contact between bones, and it acts as the fulcrum of a lever when a muscle pulls. Joints are fibrous, cartilaginous or synovial, and the synovial joints are ball and socket, hinge, pivot, gliding and saddle. Disorders such as myasthenia gravis, tetany, muscular dystrophy, arthritis, osteoporosis and gout affect the muscles, the bones or the joints.
