Question

What are examples of specialized connective tissue

Answer 1

Hyaline cartilage Fribrocartiakge Elastic cartilage Compact bone Cancellous bone Blood

Answer 2

Collagen, elastic, and reticular

Answer 3

Substance produced and secreted by connective tissue cells Compositor of matrix differs with each type of connective tissue and is specialized for the function of the tissue

Answer 4

Gel-like matrix with collagen and elastic fibers Cells include fibroblasts, mast cells, and microphages Forms a layer to which epithelial cells may bind, as in the papillary layer of the dermis Found Ariana capillary networks where it binds and protects the capillaries

Answer 5

Matrix consists of bundles of collagen fibers and little ground substance Random arrangement of collagen bundles gives this tissue structural strength to resist tearing in all directions Main cell toe if a fibroblast Found in the reticular layer of the dermis, wall of digestive tract, and fibrous capsules of organs and joints

Answer 6

Matrix contains parallel bundles of collagen fibers and little ground substance Parallel arrange,ent of collagen bundles gives this tissue great tensile strength in one direction Main cell type is a fibroblast Forms ligaments and tendons, where it’s tensile strength is able to anchor bones to each other and muscles to bone

Answer 7

Matrix consists of reticular fibers arranged in a network and loose ground substance Main cell types is reticular cells Forms flexible internal scaffolding that supports other toes of cells Found in lymph nodes, spleen, and bone marrow

Answer 8

Composed primarily of cells called adipocytes that store lipids Sparse matrix and few fibers Functions as protective padding, thermal insulation, and energy storage Found in subcutaneous layer of the skin, around the kidneys, eyeballs, heart, in the breasts, and in the abdominal cavity

Answer 9

Modified dense regular connective tissue containing a high proportion of elastic fibers Allows recoil of tissue following stretching Found in the walls of large arteries and the walls of the bronchial tubes

Answer 10

Very firm matrix containing collagen fibers; however, these fibers will not be visible in microscope slides Functions to reduce friction between bones Cells are chondrocytes located in cavities called lacunae An avascular tissue Found covering the ends of long bones within joints, costal cartilage, and cartilage of nose, trachea, and larynx

Answer 11

Matrix contains collagen fibers like hyaline cartilage, but arrangement of fibers is more regular and readily visible in the matrix Tissue is a shock absorber with high tensile strength Cells are chondrocytes in lacunae Found in the intervertebral discs, outbid symphysis, and mensci of the knee

Answer 12

This firm matrix has a greater number of elastic fibers than found in other types of cartilage Cells are chondrocytes in lacunae Very flexible cartilage Found in auricle of outer ear and epiglottis

Answer 13

Collagen fiber matrix that has been calcified to form hard tissue Cells are osteocytes which are found in small cavities of lacunae (singular is lacuna), lacunae are interconnected by network of very small canals called canaliculi (singular is canaliculus) Compact bone contains closely packed Ostend or Haversian systems An osteopath consists of a central canal (Haversian canal), surrounded by concentric rings of matrices caked lamellae (singular is lamella) Found in bones of the skeleton

Answer 14

Is lighter and less dense than compact bone Consists of plates of bonemeal called trabeculae, that form small, irregular cavities that contain red bone marrow Found deep to compact bone Red bone marrow produces blood cells in process called hematopoiesis

Answer 15

Watery matrix called plasma and no fibers Blood cells are suspended in the plasma Transport respiratory gasses, nutrients, wastes, and other substances either in the cells or dissolved in the plasma Protect the body against disease and maintain hemostasis (stops bleeding when a vessel is damaged) Found in blood vessels

Answer 16

Three types of muscular tissue: skeletal, smooth, and cardiac Individual cells in this type of tissue is called muscle fibers Contractile proteins: actin and myosin inside muscle fibers arranged to slide past each other causing contractions In skeletal and cardiac muscle, the proteins are organized into visible patterns called striations

Answer 17

Attaches to bones and produce movement Voluntary (consciously move) Muskie fibers long, slender, multinucleated, and lie parallel Contractile proteins are highly organized and visible in striations

Answer 18

Located in the walks of hollow organs such as the stomach, urinary bladder and muscular blood vessels Also called visceral muscle Spindle shaped Have a single nucleus and are involuntary No visible striations but have actin and myosin

Answer 19

Only in the heart wall Responsible for generating the force capable of pumping blood through the blood vessels Fibers are branched and have a singular nucleus, are striated, and involuntary Intercalated discs found connecting adjacent cells which allows rapid communication between adjacent cells that is necessary for the fibers to contact as a unit

Answer 20

Consists of 2 different types of cells: neuron and neurogilal cells Conducts impulses to carry information from one area of the body to another

Answer 21

Cell capable of generating and conduction an electrical impulse Consists of a cell body, one or more dendrites (receiving incoming impulses), and a single axon to conduct impulse to the next cell

Answer 22

An assortment of cells that protect, support, and insulate neurons, but do not carry impulses
