It is a group of similar cells that have the same functions in human body. Tissues outcomes in the formation of organs made primarily of tissues. (Cinnamon L. , 2)
The epithelial tissue’s function is to secret substance, prevent, cover and line ultimately all of the body’s cavities and surface. (Cinnamon L. , 71, 72)
Connective tissue is known to bind, support, and separate other organs and tissues. There are five kinds of connective tissue which are cartilage, bone, blood and loose and dense connective tissue. These kinds are in charge of supply of nerves and vascularization and nourishing the body with nutrients. There are two fibers found in this tissue called (elastic and reticular fibers) that located in places like the ear. collagen may be found in connective tissue and the bones and that provides structure and support. (Cinnamon L. , 80)
The function of muscular tissue is contracting and producing movement. Moreover, the muscle tissue controls posture, body temperature and supports soft tissues.

Simple epithelial tissue contains one single layer. Stratified epithelium contains average two or more cellular layers. Pseudostratified epithelial tissue visually contains several layers only consists of a solitary layer.
The squamous, cuboidal and columnar epithelium have distinctive cell shapes. The columnar epithelial cell is rectangular which is tall sides in length but shorts sides in width. Squamous cell is smooth, erratically and unevely formed. cuboidal epithlial cell is shaped similar to small cubes. yes, it is. Stratified squamous cell changes to a flatter figure which is creating a smooth barrier on the skin's outermost layer. Simple squamous epithelium is thin and flat figures which helps making the diffusion process between the blood and air more efficient. Simple columnar epithelium (tal, thin cells) produce enzymes. Simple cuboidal epithelium (cubelike cells) carry out active
The body is composed of cells, which form the basic unit of life. Unique cells found in the body are the stem cells. These cells are biological cells that are not specialized for particular functioning in organisms. They can be distinguished since they have the ability to differentiate or divide into multiple body cells, and their ability to replicate self. They are unique in the way they can renew themselves by undergoing cell division when inactive for a long period. It is also possible to induce stem cells to organs or tissue cells under some conditions. When the cells divide, they replenish the cells in a living organism. They serve as an internal system that repairs and replaces the tissues that are worn out.1 Dividing cells may remain as stem cells or become specialized in their functions, for instance red blood cells, brain or muscle cells.
Within skeletal muscle there are extremely small structures that form the muscle and allow contractions and movement to occur (epimysium, perimysium, endomysium, fascicles, fiber, sarcomere, sarcoplasmic reticulum and t tubules). These structures all play a role in protecting, connecting and transporting substances throughout the muscle fibers. They are also the main contributors to movement.
The lymphatic vessels are lined by the simple squamous epithelium that form the endothelium and are called lymphatic endothelial cells. The endothelium forms an interface between the lymph and the vessel wall. The endothelial cells of the lymphatic system loosely overlap, unlike the vascular endothelial cells of the blood vessels. They loosely overlap so when the fluid pressure increases in the surrounding regions they can separate to allow the excess fluid to enter the lymph capillary.
parts, and each part has its own job. The nucleus of a cell is very similar
Human skin is a multi-layered structure. It is generally divided into two layers, the epidermis and the dermis. Below the dermis a subcutaneous fat layer is found. The epidermis can be further divided into several sub-layers. These are the stratum corneum, the stratum lucidum, the stratum granulosum, the stratum spinosum, and the stratum germinativum. The stratum germinativum is usually referred to as the basal layer.
The skeletal system assists the muscular system to provide movement for the body. Certain muscles that are attached to bones contract and pull on the bones resulting in movement.
The first basic function of the muscular system is movement, which is carried out by the skeletal muscles. The primary function of the skeletal muscle is to produce voluntary gross and fine motor movement. This set of voluntary muscles provides the forces that enable the body to move. A skeletal muscle links two bones across its connecting joint. When these muscles contract or sho...
The muscular system helps the body with movement. Throughout the entire body, there are 600 skeletal muscles. In a way, the skeletal system and the muscular system work together; the nervous system tells the muscles to contract and the muscles move. Some of the functions of the muscular system are to move the body, support and protect the organs throughout the body.
The three functions of the skeletal system are to support, to allow movement, and to protect. The skeleton is the framework of the body and also cradles its soft organs, with it the body would be just a jelly mass it wouldn’t have no definite shape and would just collapse. It supports the softer tissues and provides points of attachment for more skeletal muscles to hold all of the parts of the body upright. For example, the bones of the legs as pillars to support the body trunk we stand up. It also supports the body against the pull of gravity. The skeletal allows movement. The skeletal muscle attached to the bones by tendons and uses the bones as a simple mechanical lever system to move the body and its parts. All together with the muscles
The integumentary system is composed of the skin and the structures related to the skin, which include the hair, the finger nails, the sensory receptors and the glands (Shier, Butler, & Lewis, 2009). This system has an important function since it provides protection to the body, helps to maintain body temperature, and contains sensory receptors (p.117). The skin has essential function such as regulating homeostasis and body temperature, also delaying the loss of water from deeper tissues, storing sensory receptor, synthesizing biomechanical, and discharging waste from the body (p.117). The skin has two layers: the epidermis (outer layer) and the dermis (inner layer) (p.117). There is also a subcutaneous layer or hypodermis (p.117). According to Shier, Butler, and Lewis 2009 “as its name indicates, this layer is beneath the skin and not a true layer of the skin” (p.117). This layer has the blood vessels that supply the skin (p.117).
Cells are able to grow and reproduce. Cells reproduce by splitting and passing on their genes (hereditary information) to Daughter cells. The nucleus always divides before the rest of the cell divides. Therefore each daughter cell contains their own nucleus. The nucleus controls the cells activities through the genetic material DNA. The cells in a body are all the same except the gametes they were all made from one cell, the Zygote. This is the cell that was formed when two gametes from your parents fused.
Epithelial tissue covers the surface of the human body and lines most internal cavities. Epithelial tissue is found in the body’s skin, lining of the stomach and intestines, the kidney, and glands, as well as other locations within the body (Amsel, 2012). The two types of epithelial tissue are (1) covering and lining epithelium and (2) glandular epithelium. The covering and lining epithelium are found lining the integumentary, digestive, cardiovascular, and respiratory systems as well as the ventral body cavity and the organs this cavity houses (Hoehn, et al., 2007, p. 118). The glandular epithelium is found within the glands of the entire human body. Not only are their two types of epithelial tissue found in the human body, there are also multiple classifications and various shapes. These classific...
Tissue engineering is the study of the growth of connective tissues or cells to produce a fully functioning organs in the patient. Instead of implantation, tissue engineers make an attempt to create organs that will suit the patient without rejection from the immune system. Tissues are extracted from...
Histopathological samples are examined in vivo where the relationship between the cells is maintained and observable. These can be cross sections of small organs or slices of larger ones. This results in a large number of cells being available and their cell-to-cell interactions apparent for examination.
The External or Outer Ear - comprises of the auricle or pinna which is the fleshy part of the outer ear. It is cup-shaped and collects and amplifies sound waves which then passes along the ear canal to the ear drum or tympanic membrane. The rim of the auricle is called the helix and the inferior portion is called the lobule. The external auditory canal is a carved tube and contains a few hair and ceruminous glands which are specialized sebaceous or oil glands. These secrete ear wax or cerumen. Both the hairs and the cerumen help prevent dust and foreign objects from entering the ear. A number of people produce large amounts of cerumen, and this sometimes cause the build up to be impacted and can bri...
