The lungs are made up of many types of tissue; the cartilages‚ ciliated epithelium‚ smooth muscle‚ squamous epithelium‚ elastic fibres and goblet cells and glandular tissue. The cartilage is a very stiff and flexible tissue‚ which doesn’t contain air vessels. It is found in trachea‚ bronchus‚ bronchiole and alveolus‚ and it has a structural role. It support‚ and gives strength to trachea and bronchi. It holds the airways open for the resistance with little airway. This prevents it from collapse

types of tissue found in animals: connective‚ muscle‚ nervous‚ and epithelial. We are going to go into muscle tissue. The cells of muscle tissues are called fibers. There are three types of muscle tissue and they are skeletal‚ cardiac‚ and smooth. All types can go though hypertrophy (enlargement or overgrowth of an organ or part of the body due to the increased size of the constituent cells). Muscle fibers contract due to the interaction of the contractile proteins‚ actin and myosin. Muscle contraction

Muscle Tissue 1. How is muscle tissue categorized? Muscle tissue is categorized by its shape‚ the number of nuclei‚ and the mechanism of stimulation. 2. a. Click the Smooth Muscle Tissue. Identify each of the following: Nucleus----- Smooth Fiber Muscle------------------ b. Describe smooth muscle control (voluntary or involuntary). Involuntary c. Name some smooth muscle functions (click the “Tissue Locations” button). Smooth

Muscle tissue Muscle tissue has a ability to relax and contrast and so bring about movement and mechanical work in various parts of the body. There are other movements in the body too which are necessary for the survival of the organism such as the heart beat and the movements of the alimentary canal. Muscles can be divided into three main groups according to their structure * Smooth muscle tissue. * Skeletal muscle tissue. * Cardiac (heart) muscle tissue.

The depolarisation and repolarisation that takes place within a cell from that occurs gives rise to voltage of waveforms. With the human body each cell at this present time is generating electrical impulses like a voltage generator‚ which is a basic source of all the bioelectric potentials. With these bioelectric potentials they produce ionic voltages produced by the coordination of electrochemical activity within numerous cells. When the cells are in line the charges tend to migrate through the

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
