correctly identify this tissue type and then label the features of the tissue
right: chondrocytes bottom: collagen fibers name this tissue type: fibrocartilage
place a single word into each sentence to make it correct
- epithelial tissue can be CLASSIFIED according to cell shape and number of layers - one layer of cells is called SIMPLE, and more than one layer is called stratified - thin, flat, scaly cells are SQUAMOUS - cuboidal cells are either rounded or SQUARE in shape - columnar cells are taller than they are WIDE - pseudostratified cells look like more than one layer because of the arrangements of the cells' NUCLEI
correctly identify the tissue type and then label the features of the tissue
left side- cuboidal cells right side- connective tissue name this specific tissue type: stratified cuboidal epithelium
determine which connective tissue type each image below represents. then click and drag the labels matching them up with the correct tissue type
1st pic (crusty blue and white): bone - concentric lamellae - site of calcium and phosphorous storage - provides a protective enclosure for viscera 2nd pic (wave blue and white): dense regular connective tissue - resists tensile forces from one direction - main tissue found in the tendons that help muscles attach to bones 3rd pic (dark pink and white): dense irregular connective tissue - resists tensile forces from several directions - found in the deeper layer of the skin
determine which muscular tissue type each image below represents. then click and drag the labels placing them in the correct category
1st pic (pink w white lines and purple ovals): skeletal muscle - voluntary - moves the skeleton - multinucleated 2nd pic (pink and white mix): cardiac muscle - nucleus surrounded by glycogen - connected by intercalated discs 3rd pic (pink mix w purple ovals): smooth muscle - mostly found in the viscera - helps propel content through a tubular organ
determine which connective tissue type each image below represents. then click and drag the labels matching them up with the correct tissue type
1st pic (purple and blueish): hyaline cartilage - attaches the ribs to the sternum (breastbone) - provides a low-friction surface for ease of joint movement - holds open passaged so we can breathe 2nd pic (blue and light blue): elastic cartilage - helps collect sound waves - allows structures to stretch and return to original shape 3rd pic (pink and purple): fibrocartilage - found in the intervertebral discs - resists compressive forces in the spine
determine which connective tissue type each image below represents. then click and drag the labels matching them up with the correct tissue type
1st pic (purple and navy): reticular connective tissue - provides supportive framework for the spleen - found in the bone marrow and lymph nodes 2nd pic (red and pink): areolar tissue - forms the basement membrane of epithelia - found in the fascia that holds muscles together - forms the serous membrane of the lungs 3rd pic (pink and white): adipose tissue - stores energy - provides thermal insulation

drag each label into the appropriate position to identify whether the statement depicts something true or false about the specimen pictured below
true: - contains connective tissue - visible directional orientation of collagen fibers - found in areas where bones are joined via cartilage - same tissue category as blood - larger proportion of extracellular matrix to cells - functions to resist shock false: - seen in tendons - contains dense irregular connective tissue - contains a perichondrium - chrondrocytes in clusters of 3-4 arranged in clumps
identify the tissue type shown in the image below. then click and drag each label into the appropriate category to determine whether the statement is true or false regarding the tissue
true: - contains epithelial tissue - located in the kidney tubules - secretes/absorbs substances to/from the lumens formed by this tissue - exposed to the environment or internal body surface false: - contains stratified epithelium - comprises the inner surfaces of the blood vessels - contains a large amount of extracellular matrix - is highly vascular - provides fast-acting lines of communication between body structures - well-suited for resisting frictional forces
drag each label into the appropriate position to identify whether the statement depicts something true or false about the specimen pictured below (neuron)
true: - electrically excitable - can receive and transmit electrical signals - when excited, the cells shown conduct electrical impulses to other cells - protected by neuroglia - the cells shown are stimulated by changes in membrane potential false: - the cells shown are held together by gap junctions - functions principally to produce heat and move body segments - these cells are considered to be contractile - characterized by a high proportion of ground substance and fibers - forms the lumenal lining of the digestive tract
