10
Q
A
transitional epithelium: ureter

11
Q
A
areolar connective tissue
- matrix contains all 3 fibers types. fibroblasts, mast cells, macrophages and other white blood cells found
- location:distributed throughout body loosely binding adjacent structions:forms lamina propria that underlies all epithelia in body; surrounds blood vessels, nerves, muscles
12
Q
A
adipose tissue: external ear
- closely packed adipocytes(fat cells) within a sparse matrix. each adipocyte is filled with a large fat droplet causing the nucleus to be pushed to the edge of the cell
- found trhoughout body:hypodermis of skin; eyeballs, mammary glands, within abdomen, within fascial planes seperating muscle layers
13
Q
A
reticular conective tissue: lymph node
- matrix composed of reticular fibers loosely distributed within a gel like gound substance. cellular components: fibroblasts, lymphocytes, and other blood cells
- location:forms internal framework of many lympoid organs: spleen, bone marrow, lymph nodes
14
Q
A
dense irregular connective tissue: submucosa of large intestine
- distinguished by irregular arrangement of fibers densely packed in multiple directions. composed primarily of collagen fibers with some elastic fibers.
- location: retifular layer of dermis of skkin, submucosa of digestive tract, fibrous capsules of organs and joints
15
Q
A
dense regular connective tissue:tendon
- densely packed fibers,primarily collagen, arranged parallel to each other with nuclei of the fibroblasts also aligned parallel.
- location:tendons, most ligaments, aponeuroses
16
Q
A
elastic connective tissue: aorta
- connective tissue with densely packed elastic fibers. notice appearance of dark staining elastic fibers. Here these fibers are within the smooth muscle layer of the wall of the aorta.
- location:found within body wall of arteries; throughout trachea and bronchial tree; located within some ligaments in the neck region
17
Q
A
hyaline cartilage connective tissue:trachea
- cartilage cells(chonodrocytes) located within spaces in the tissue matrix
- forms most of the embryonic skeleton, covers teh ends of long bones in joint cavities forms the costal cartilages, the cartilages of nose, trachea and bronchial tree and most laryngeal cartilages
18
Q
A
elastic cartilage connective tissue:epiglottis and external ear
- as in hyaline cartilage, the chondrocytes sit in spaces(lacunae) within the tissue matrix
- dark purple strands
19
Q
A
fibrocartilage connective tissue:tendon
- gelatinous matrix densely pacekd with thick collagen fibers
- form the intervertebral discs, pubic symphysis, articular discs, tendons
20
Q
A
compact bone connective tissue
- tissue composed of a hard, calcified matrix contianing many collagen fibers
- found in the shaft of long bones, the external portion of flat short and irregular shaped bones, and the externl portion of the epiphyses
21
Q
A
spongy bone
- composed of the same material as compact bone
- arranged into small beams of bony tissue
- located in interal regions of epiphyses, as well in the internal potins of flat, short, and irregular shaped bones
22
Q
A
blood smear
- erythrocytes(red blood cells), leukocytes(white blood cells), and plateleys in a fluid matrix
