and 2 Fill in the bianks All tisues consist of two main components which consists of a gelatinous substance called numerous different 3 An epithelial tissue that has one layer of rectangular cells would be classified as a. stratified squamous epithelium b. simple cuboidal epithelum C stratfied columnar epitheium. d simple columnar epithelium 4 How do pseudostratified ciliated columnar epithelium and transitional epithelium differ from other types of epithelia? 5 Truelfase: Mark the following statements concerning connective tissue proper and cartilage as true (D or false (F). If the statement is false, correct it to make it a true statement. Adipocytes contain a large lipid droplet in their cytoplasm. The primary element in dense regular collagenous connective tssue is ground substance Bundles of collagen fibers are arranged parallel to one another in dense Loose connective tissue contains all three protein fiber types Fibrocartilage has a smooth, glassy appearance due to a large amount of ground substance and lew visibie iregular collagenous c connective tissue protein fibers 6 Which of the following best characterizes the extracellular matrix (E a Bone tissue ECM consists of only calciun hydroxyapatite crystals b. Bone tissue ECM consists of calcum hydroxyapatite crystals and collagen fibers C. Bone tissue ECM consists of only collagen fibers d Bone tissue ECM consists of collagen, elastic, and reticular fbers 7 Circle all that apply Which of the following characteristics apply to skeletal muscle tissue? a Striated b. Nonstriated c Multinucleate d Uninucleate e Contains intercalated discs f Voluntary g Involuntary h. AutorhythmicExplanation / Answer
2] cells and ground substance
extracellular matrix and protein fibers.
3] Option [b] simple cuboidal epithelium
Stratified epithelial cells consist of two or more layers of cells arranged on a basement membrane whereas simple epithelial cells consist of a single layer of cells. Cuboidal cells are rectangular and cube-shaped and columnar cells are elongated and taller than they are broad.
4] Pseudostratified ciliated columnar epithelium have cilia at their free, apical surface. Mucus-secreting unicellular gland cells, called goblet cells, lie among the ciliated cells. These epithelial cells form a lining in the lumen of the trachea.
Transitional epithelium is a type of stratified epithelial tissue which is made up of multiple layers of epithelial cells which can contract and expand as needed. Hence they provide a degree of distention to the organs where they are found eg they form the mucosal lining of the uterus, a portion of the urethra and the urinary bladder. This helps these organs to distend or expand if needed.
5] a] True [ adipose tissue contain fat droplets]
b] False [ the primary element is the densely packed collagen fibers which are arranged in parallel]
c] False [ the collagen fibers are arranged irregularly and not in parallel ]
d] True[ they are most common and holds organs in place and attaches epithelial tissues to other tissues. They include areolar, adipose and reticular tissues. Given their wide range of sructure and function, these tissues contain all three types of fibers.
e] True [ the matrix is mostly made of cartilage to give it tensile strength.
6] Option [b] bone tissue ECM consists of hydroxyapatite crystals and collagen fibers. They also contain osteocalcin, proteoglycans, osteonins and other organic substances to give it strength and endurance].
7] The characteristics that apply to skeletal muscles are -- a] striated, [c] multinucleate, and [f] voluntary
Visceral or involuntary muscles are uninucleate and unstriated.
Cardiac muscles are striated , multinucleate, contain intercalated discs and are autorhythmic.
