The cell membrane is made up of fats‚ proteins‚ lipids‚ and carbohydrates‚ and is a permeable structure. However‚ this permeation is very discerning because it only lets certain things pass through it. The cell membrane has a layer of phospholipids with hydrophobic ends and hydrophilic tops. The “tails” are made out of phosphate‚ while the “heads” are made up of two strings of fatty acids. There are two layers of these phospholipids‚ called the “bilayer”‚ and the tips of each phospholipid are facing

Epithelial tissue Covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection‚ secretion‚ absorption‚ and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt‚ dust‚ bacteria and other microbes that may be harmful. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the

Music and its Functions and Roles Music has always been an integral part of human civilization. It is what binds individuals to their culture‚ people to their country. From the majestic stories of India to the concert halls of Vienna to the radio station playing mariachi music here in LA‚ music pervades our lives. Since our beginnings‚ music has accompanied rituals and ceremonies‚ and as time passed‚ began to fill other roles in religion‚ society‚ education‚ and entertainment. Within these different

Tissue engineering By Nathan. F Introduction Tissue Engineering is the use of a combination of cells‚ engineering and materials methods‚ and suitable biochemical and physio-chemical factors to improve or replace biochemical functions. The objective of tissue engineering is to create living body parts that will fully integrate with the recipient’s body. Tissue engineering mostly associated with applications that repair or replace portions of or whole tissues. For example bone‚ cartilage

Types of Tissues Stacy Sisler HS 120‚ Section 03 Unit 2 Seminar Kaplan University Jan. 17‚ 2011 Types of Tissue A tissue is a group of cells that have a similar shape and function. Different type of tissues can be found in different organs. In humans‚ there re four basic types of tissue: epithelial tissue‚ connective tissue‚ muscular tissue‚ and nervous tissue. There may be various sub-tissues within each of the primary tissues. Epithelial tissue covers the body

There are four 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

Tissue Types Amy Chanda Morrison Colorado Christian University Our bodies have four different types of tissues. They are epithelial‚ connective‚ muscle and nervous. Each one has a specific job to do to keep the body in homeostasis. Patton stated “homeostasis is the relatively constant state maintained by the body” (pg.19). He also stated that “the precise and constant chemical composition of the internal environment must be maintained within very narrow limits‚ or sickness and death will result”
