In recent years, Dubai’s real estate market has boomed, attracting investors from all over the world. Because of this growth, there is a high demand for real estate agents and brokers. […]
Functional Dynamics of Subintimal Tissue
Functions of subintimal tissue: Due to high elasticity of elastin fibres and their concentration in mobile parts of the synovial membrane, the subintimal tissue prevents the nipping of synovial membrane during movements. FUNCTIONS OF THE SYNOVIAL MEMBRANE 1.It performs three functions:2.It takes part in the production of synovial fluid.3.It helps in absorption of the fluid.4.It […]
WHAT IS SECONDARY CARTILAGINOUS JOINTS (SYMPHYSES)
They show following features :- 1.These joints are mainly seen in axial bones. 2.These joints are formed by white fibro-cartilage which connects the articular surfaces covered by hyaline cartilage.3.They are slightly movable and mobility depends upon sufficient amount of white-fibro cartilage.4.Frequently a cavity is seen which is not lined by synovial membrane. 5.This cavity contains […]
A Study Of Joints And Its Classification
When two or more bones or cartilages come in contact with each other an articulation or a joint is formed. The study of joints is known as arthrology. The previous term syndesmology is not correct because it means study of ligaments (G. Syndermos = ligament) which only form a component of a joint. The joints […]
SUPERFICIAL FASCIA OR SUBCUTANEOUS TISSUE
It is a membranous lamina consisting of fibro-areolar tissue, the meshes of which are filled with fatty or adipose tissue. Therefore, it is also known as Panniculus adiposus. A) DEEP FASCIA It is a dense elastic membrane forming coverings for the muscles and in some cases affording for them blind surfaces for attachments. It is […]
STRUCTURES RELATED TO THE MUSCLES
TENDON They are tough whitish cords/straps varying in length and thickness, and are almost inextensible. They comprise numerous parallel Fascicles (bundles) of collagen fibres and tendon cells surrounded by firbo-areolar tissue which helps to bind them together. This fibro-areolar tissue is called interfascicular tissue or endo-tenon. At the surface of the tendon the fibro-areolar tissue […]
METHODS OF STUDY OF SKELETAL MUSCLE
METHODS OF STUDY OF SKELETAL MUSCLE – ACTIONS Following methods are employed for study of skeletal muscle actions: I.ELECTROMYOGRAPHY It is throwing much new light about the functions of an individual muscle or groups of muscles.It consists of putting electrodes into the muscle to be tested. After this, the individual is asked to perform a […]
PARTS OF A SKELETAL MUSCLE
PARTS OF A SKELETAL MUSCLE : Grossly each skeletal muscle is composed of following parts: Origin (Proximal attachment):It is the proximal attachment, which usually remains fixed during contraction of the muscles.Skeletal muscles usually take origin from the following structures :- Bones (most important).1.Fasciae (e.g., Muscles of facial expression, serratus anterior).2.Ligaments (e.g., Trapezius from ligamentum nuchae […]
