main tissues of the body. In this assignment I’m going to talk about the structure of the main tissues which are found within the body as well as what their role is in the terms of two named organs of the body. Tissues are a collection of similar cells that group together to carry out a specific function within the body. There are four different types of tissue found in the human body which include; epithelial tissue; connective tissue; muscle tissue and nerve tissue. The first type of tissue found
Premium Muscle Tissues Cardiac muscle
Connective Tissue As the name implies‚ connective tissue serves a "connecting" function. It supports and binds other tissues. Unlike epithelial tissue‚ connective tissue typically has cells scattered throughout an extracellular matrix. Loose Connective Tissue In vertebrates‚ the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Loose connective tissue is named based on the "weave" and type

Notes on histology Histology Lecture 1 Histology is the study of tissues: in our case‚ it means study of tissues which make up the human body. Tissue is defined as a group of cells which perform a common function. All the cells in a given tissue are not necessarily identical or similar e.g. blood is a type of connective tissue but it has many different types of cells. However‚ tissue also contains two other components i.e. ground substance (or matrix) and fibres. Despite the complexity of

Unit 3 Lecture Study Guide 1. List the 4 primary tissue types and give the general characteristics and functions of each one. 1) Epithelial: Covers the body‚ lines the cavities‚ tubes ducts and blood vessels‚ covers the organ inside the body cavity 2) Connective: most abundant& widely distributed‚ connect‚ bind and supports structures‚ insulates‚ and transports substances. 3) Muscle: associated with the bones of the skeleton‚ the heart and in the walls of the hollow organs

C) muscle tissue. D) basal tissue. E) apical tissue. 3) Characteristics of epithelia include all of the following except A) attachment. B) avascularity. C) regeneration. D) polarity. E) extracellular

List the 4 primary tissue types and give the general characteristics and functions of each one. Nerve Tissue: transmit nerve impulses; coordinates and regulates body activities‚ bind and support nerve tissue; carry on phagocytosis; connect neurons to blood vessels‚ changes shape from squamous to cuboidal Epithelial Tissue: covers all free body surfaces and lines organs‚ anchored to connective tissue by basement membrane‚ lacks blood vessels‚ can reproduce Connective Tissue: connects‚ supports

There are not any real safety concerns for this lab other than making sure correct use and care of the microscope is used.

composed of 3 major layers: the epidermis‚ the dermis‚ and the hypodermis. The epidermis is where the epithelial cells are located‚ the dermis are where connective tissues‚ nerves‚ and blood vessels start to appear‚ and the hypodermis is where fat cells are located. The dermis of both tissues are divided into 2 layers of connective tissue. The connective tissue right below the

In this piece of work I’ll talk about these types of cells: Epithelial Tissues: Epithelial are the lining of internal and external surfaces and body cavities‚ including tubes/channels (ducts) carrying secretions from glands. Epithelial tissues can be made of several layers of cells (called compound epithelia)
