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 […]
CLASSIFICATION OF SKELETAL MUSCLE
Skeletal muscles are classified into various groups according to following scheme : I.According to the relative colour of skeletal muscle cells: In lower vertebrates for example fish and chicken the skeletal muscle cells are red (leg of chicken) or pale (breast of chicken). The distribution between the red and white muscle cells is clearly visible […]
What is Muscle and its Classification?
The word muscle is derived from Latin word mus which means a mouse. Most of muscles of vertebrates resemble a mouse in their external appearance, the tail of the mouse representing the tendon of the muscle. Usually the muscle tissue forms about one half of the total mass of an average vertebrate. Functionally the muscles […]
Types of BONES And CARTILAGES
OSTEOLOGY: It is the branch of anatomy which deals with the study of bones and cartilages.The frame work of human body is composed of bony and cartilagenous tissue called Skeleton. The skeleton is of two types:1.Exo-skeleton: It is that part of skeleton which is present in relation with the skin, e.g., Enamel of tooth.2.Endoskeleton: It […]
PARTS OF A DEVELOPING LONG BONE
Diaphysis: It resembles the shaft of a long bone. The centre of ossification appears in the 7th week of Intrauterine life. The ossification centre is called primary ossification centre. It resembles the ends of a long bone. The centre of ossification usually appears after birth at the age of one or two years except the […]
