Outline the structure of the main tissues of the body Below, I will produce an assignment on the main tissues of the body. There are four main tissues and I will be explaining them in detail below, using key words, which will show I understand the tissues and what the key words mean in this context. The four main tissues are: * Epithelial * Connective * Muscle * Nervous Epithelial Epithelia are the lining of the internal and external surfaces and cavities. This includes tubes or channels, which would be carrying secretions from the glands in our body. The epithelia can be made of several layers, which would be made of cells.
It contains a number of glycoprotein receptors through which platelets react with aggregating agents, inhibitors, coagulation factors and consequently the vessel wall and each other. Some of the important glycoproteins include GP1a and GP1b. GP1a binds to collagen and GP1b binds to von Willebrands factor 2. It also contains phospholipids, which act as a surface for interaction with specific components of coagulation biochemistry, such as factor II and factor X The surface connected open canalicular sytem (SCOCS) is a network of channels throughout the interior of the platelet formed from the invaginations of the membrane. These channels increase the surface area of platelet exposed to plasma.
Nervous tissues are the main component of the nervous system, which regulates and controls body functions. 4. The appendages of the skin include the hairs, nails, sweat glands and the sebaceous glands. They are all associated with the skin and they serve a particular function. The nails protect the nerve endings while the sebaceous glands lubricate the skin and hair.
Lab 2: Identification of Tissues Part A: The Four Main Tissue Types Define tissue: an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism. Identify the four main tissue types and provide the function for each: Tissue Type | Function | Epithelial tissue | protects the body from moisture loss, bacteria, and internal injury | Connective tissue | provides structure and support to the body | Nervous tissue | forms the nervous system, which is responsible for coordinating the activities and movement of your body through its network of nerves | Muscle tissue | Different from the other tissues in that it contracts. Muscle tissue comes in three types: cardiac, smooth, and skeletal. Those muscle tissues are made up of muscle fibers. The muscle fibers contain many myofibrils, which are the parts of the fiber that actually contracts | Part B: Epithelial Histology Based on shape, identify the three types of epithelial tissues and provide a description of each: Epithelial Tissue Type | Description | Squamous | single layer of flat cells; scale like | Cuboidal | single layer of cubed shaped cells | Columnar | tall, column-shaped | Identify where each of the following types of epithelial tissues are found: Epithelial Tissue Type | Location | Simple squamous | found in lungs and kidneys | Simple cuboidal | Is found covering the kidneys, lining the kidneys tubule, and lining some glandular ducts.
To accomplish the primary functions of the nervous system there are neural pathways to transmit impulses from receptors to the circuitry of the brain, which manipulates the circuitry to form directives that are transmitted via neural pathways to effectors as a response. II. SENSATION A. Sensation is a conscious or unconscious awareness of external or internal stimuli. Perception is the conscious awareness and interpretation of sensations.
Introduction: The human body has many cells and tissues. In this report, Epithelial Tissue will be examined for what it is, how they functions in a human body, and what role they do in the organs. Description: Epithelial Tissues are one of the four major tissues in a human body. There are many types of Epithelial Tissue; there is the Squamous, Cuboidal, Columnar, and the Glandular Epithelium. There are two main types of this tissue one is the simple epithelium and the other is the stratified epithelium.
The paraventricular nucleus for instance contains oxytocin and vasopressin (also called antidiuretic hormone) neurons which project to the posterior pituitary, but also contains neurons that regulate ACTH and TSH secretion from the anterior pituitary, as well as gastric reflexes, maternal behavior, blood pressure, feeding, immune responses, and temperature. The hypothalamus co-ordinates many hormonal and behavioural circadian rhythms, complex patterns of neuroendocrine outputs, complex homeostatic mechanisms, and many important behaviours. The hypothalamus must therefore respond to many different signals, some of which are generated externally and some internally. It is thus richly connected with many parts of the central nervous system, including the brainstem reticular formation and autonomic zones, the limbic
The lymphatic system filters out organisms that cause disease, produces certain white blood cells and generates antibodies. It is also important for the distribution of fluids and nutrients in the body, because it drains excess fluids and protein so that tissues do not swell up. "Lymph" is a milky body fluid that contains a type of white blood cells, called "lymphocytes," along with proteins and fats. Lymph seeps outside the blood vessels in spaces of body tissues and is stored in the "lymphatic" system to flow back into the bloodstream. Through the flow of blood in and out of arteries, and into the veins, and through the lymph nodes and into the lymph, the body is able to eliminate the products of cellular breakdown and bacterial invasion.
The tunica serosa is composed connective tissue covered by a simple squamous epithelium that is continuous with the lining of the body cavities. Tunica serosa – connective tissue with a thin layer of epithelia tissue (prevents sticking to lining of body cavities) some of the organs
The body system approach is the study of the body’s organs and how they function together inside the body. Body system approach is used when studying the bodies systems such as the respiratory system, circulatory system, to see how they function in the body. Medical specialty is the study of the human body for medical uses. Medical specialty is divided into many different categories such
