According to shape and layer of cells, epithelial tissue which are present in human body is divided in two main types: 1. Simple Epithelial Tissue 2. Compound Epithelial Tissue. Type # 1. Simple Epithelium Tissue: I. Pavement (Squamous) (Fig. 1.20A): Description: It is composed of a single layer of large flat cells placed on a thin basement membrane. Distribution: It [...]
In this article we will discuss about:- 1. Distribution of Skeletal Muscle 2. Origin and Development of Skeletal Muscle 3. Features 4. Histological Structure 5. Blood Vessels, Lymphatics and Nerves. Distribution of Skeletal Muscle: The skeletal (voluntary and striated) muscle fibres are multinucleated cylindrical structures having a clear display of longitudinal and cross-striations. This muscular tissue is responsible for voluntary [...]
In this article we will discuss about:- 1. Origin and Development of Visceral Muscle 2. Histology of Visceral Muscle 3. Distribution 4. Fine Structure 5. Blood Vessels, Lymphatics and Nerves. Origin and Development of Visceral Muscle: The smooth muscles are mesenchymal in origin. The mesenchymal cells first start to stretch out. The nucleus becomes elongated, and myofilaments appear in the [...]
