Contains two major cell types: neurons & supporting cells. Functions include secretion & absorption. Its rows of chondrocytes (a cartilage feature) alternate with rows of thick collagen fibers (characteristic of dense regular connective tissue). Produce hormones, messenger chemicals that they secrete by exocytosis directly into the extracellular space. Example of Homeostasis maintained by a negative feedback, Thickening of epidermis to callus in response to friction. Dispose of dead tissue cells, & they are central actors in the immune system. Exposed to the air & is a dry membrane. non-cellular, adhesive sheet consists largely of glycoproteins secreted by the epithelial cells plus some fine collagen fibers. (neutrophils, eosinophils, lymphocytes), & other cell types that are concerned with tissue response to injury. The human skeleton is comprised of 206 bones. So they work in pairs of flexors and extensors. Form the flesh of the body.m, as they contract they pull bones or skin causing body movements. Consequently, adipocytes, commonly called adipose or fat cells, account for 90% of this tissue's mass. Deep to the Basal Lamina, both form the basement membrane, which reinforces the epithelial sheet, helps it resist stretching & tearing, & defines the epithelial boundary. Red cells are very important to the human body, because they carry oxygen to the body's tissue, and they also carry carbon dioxide out to the lungs where it is eliminated. - Many bones give your body the shape you are familiar with. Typically, they are branching cells with cytoplasmic extensions or processes that enable them to Respond to stimuli (via process called dendrites)Transmit electrical impulses over substantial distances within the body (via processes called axons. Large, irregularly shaped cells that avidly phagocytize a broad variety of foreign materials, ranging from foreign molecules to entire bacteria to dust particles. moist membranes found in closed ventral body cavities. They regenerate from below, that is, the basal cells divide & push apically to replace the older surface cells. gristle, is the most abundant cartilage in the body. The muscles of the body are all attached to the bones. Musculoskeletal disorders. Receives its nutrients by diffusion from blood vessels located in the connective tissue membrane (perichondrium) surrounding it. A skeletal muscle may attach a bone to another bone (often across a joint) or a bone to another structure, such as skin. As the contraction of the muscles occurs, the bones that are connected will react in a lever movement. The reason the hypodermis acts as a shock absorber is that _______, Major part is adipose, serves as an effective shock absorber, Dendritic cells - activate the immune system. Constructed primarily of its self named fibrous protein. Found in areas subjected to wear and tear, Pull on bones or skin causing body movements, Virtually no functional regenerative ability, The role of brown fat is to warm the body; whereas, the role of white fat is to store nutrients, Tendons and ligaments are composed mainly of dense irregular connective tissue, Goblet cells are found within pseudostratified ciliated columnar epithelium, Epithelial tissues always exhibit polarity; they have a free surface and a basal surface, Epithelial cells contain both blood vessels and nerve fibers, Adipose tissue is made up of pseudostratified columnar epithelial cells, Merocrine glands produce secretions by accumulating secretions internally until cell ruptures, Cartilage tissue tends to heal less rapidly than bone tissue, Intercalated discs and striations are both characteristics of skeletal muscle, Cartilage has good regenerative capacity, while most epithelial tissues do not, Squamous cells are flattened and scale-like when mature, Functions of connective tissues include binding, support, insulation, and protection, Blood is considered a type of connective tissue. mature cells maintain the health of the matrix. Heart muscle cells would tend to separate without ________. Nearly identical to hyaline cartilage. Causes Share These cells are mostly associated with absorption & secretion, & the digestive tract lining has two distinct modifications that make it ideal for that dual function. its cells have no visible striations. The tendon uses this force to initiate movement of the connected bone and associated joint. found where strong support & the ability to withstand heavy pressure are required. The arrector pili muscle's predominate, useful function in humans is to ________, Assist in the release sebum from nearby sebaceous glands, The composition of the secretions of the eccrine glands is ________, 99% water, sodium chloride, trace wastes, and vitamin C. also acts as a scaffolding along the epithelial cells can migrate to repair a wound. Anatomical movements are no different. Forms the lining of the urinary organs, which stretch as they fill with urine. It is made up of 26 disc-shaped vertebrae. Forms a labyrinth-like stroma, or internal framework, that can support many free blood cells (mostly lymphocytes) in lymph nodes, the spleen, & bone marrow. The majority of muscles in the leg are considered long muscles, in that they stretch great distances. or planes parallel to them. However, elastic cartilage has many more elastic fibers. Cells vary in height. skeletal muscle. https://www.rchsd.org/health-articles/bones-muscles-and-joints-2 This epithelium forms the walls of the smallest ducts of glands & of many kidney tubules.
