Chapter 5 epith
Epithelial tissue covers surfaces and lines cavities throughout the body. There are three main types - covering/lining epithelium, glandular epithelium, and sensory epithelium. Epithelial cells are closely packed, rest on a basement membrane, and lack blood vessels. They are classified based on cell shape (squamous, cuboidal, columnar), number of cell layers (simple or stratified), and surface features like microvilli. Common simple epithelia include squamous, cuboidal and columnar found in skin, kidneys, and digestive tract. Stratified epithelia have multiple layers and are found in skin, mouth, and vagina. Glandular epithelia are specialized to secrete substances either
The Epithelial Tissue
Epithelial tissue lines body surfaces and cavities and forms glands. It has several key characteristics: it protects underlying tissues, regenerates quickly, is avascular, and is polarized with selectively permeable cells. Epithelial tissue includes glandular epithelium which forms two types of glands - endocrine glands that release secretions into the bloodstream and exocrine glands that secrete into ducts leading outside or inside the body. Exocrine glands are classified by their secretory mechanisms and structures.
Epithelium
This document provides information about epithelium:
- Epithelium is a primary tissue that covers body surfaces, lines cavities, and forms glands. It develops from all three germ layers and has chief characters of being predominantly cellular, having adhesion, and a basement membrane.
- Epithelium is classified as unilaminar (simple) or multilaminar (stratified). It performs important functions like secretion, absorption, transportation, protection, sensation, and lubrication. Examples of different epithelial tissues are provided.
Histology Lab Slides
Here are the tissues and structures I see in this slide:
- Simple squamous epithelial tissue - the single layer of flat cells
- Stratified squamous epithelial tissue - the multi-layered epithelium with basal and apical layers. The apical layer contains keratinized cells that will be sloughed off.
Epithelial tissue
Epithelial tissue forms the covering of all body surfaces, lines cavities and organs, and forms glands. It is composed of tightly packed cells with one free surface and no blood vessels that regenerate quickly. Epithelial tissue can be squamous, cuboidal, or columnar in shape and simple, stratified, or pseudostratified in number of cell layers. Glandular epithelium secretes products through exocrine glands that can be classified by structure and secretions, such as merocrine, apocrine, or holocrine glands.
Connective tissue
Connective tissue is the most abundant tissue in the body and fills spaces between other tissues. It has several components including fibers, ground substance, and cells. The document categorizes connective tissue and describes its various cell types such as fibroblasts that produce collagen fibers, undifferentiated mesenchymal stem cells that can differentiate into other cell types, pigment cells like melanocytes that produce pigment, fat cells that store lipids, and immune cells including lymphocytes, plasma cells, and macrophages. Connective tissue provides structure and support to the body.
Tissues
The document discusses the four main types of tissues in the human body - epithelial, connective, nervous, and muscle tissue. It provides details on the different subtypes of each tissue, including their structure, function, and location in the body.
Epithelial tissue 1
This document provides information on the different types of epithelial tissue:
- Epithelial tissue consists of one or more layers of cells that cover external and internal surfaces of the body. It is classified as simple or compound epithelium.
- Simple epithelium is only one cell layer thick and includes squamous, cuboidal, columnar, ciliated, and pseudostratified types. It functions in absorption, secretion, and filtration.
- Compound epithelium has multiple cell layers and includes stratified and transitional epithelium. It provides protection to underlying tissues. Glands are specialized epithelial cells or groups of cells that secrete substances.

Finally, it covers conduction defects, implications for congenital heart anomalies like ASD and VSD, and considerations for cardiac surgery.
Cardiac conduction system
The cardiac conduction system is made up of four main structures that stimulate contraction of the heart muscle in a coordinated way. The sinoatrial node acts as the pacemaker and initiates electrical impulses throughout the heart. The atrioventricular node receives impulses from the atria and slows conduction to allow for proper atrial contraction before ventricular contraction. Impulses then travel through the atrioventricular bundle and Purkinje fibers to coordinate simultaneous contraction of the ventricles. An electrocardiogram is used to measure the electrical activity of the heart and detect any abnormalities.
