Description

Reilynn Martin Anatomy & Physiology Lab 6 PRE-LAB QUIZ: 1. Epithelial tissues can be classified according to cell shape. ____________ epithelial cells are scalelike and flattened. C) Squamous 2. All connective tissue is derived from an embryonic tissue known as: C) mesenchyme 3. All the following are examples of connective tissues except: C) neurons 4. Of the two major cell types found in nervous tissue, neurons are highly specialized to generate and conduct electrical signals. REVIEW SHEET: 1. List the following in order from least complex to most complex: (organ, cell, tissue, and organ system) Cells, Tissues, Organs, organ system 2. Define histology: The study of the microscopic structure of tissues 3. Use the key choices to identify the major tissue types described below: 1. Lines body cavities and covers the body’s external surface: B) Epithelium 2. Pumps blood, flushes urine out of the body, allows one to swing a bat: C) Muscle 3. Forms endocrine and exocrine glands: B) Epithelium 4. Anchors, packages, and supports body organs: A) Connective Tissue 5. Classified based on the shape and arrangement of the cells: B) Epithelium 6. Derived from mesenchyme: A) Connective Tissue 7. Major function is to contract: C) Muscle

8. Transmits electrical signals: D) Nervous Tissue 9. Consists of cells within an extracellular matrix: D) Nervous Tissue 10. Most widespread tissue in the body: A) Connective Tissue 11. Forms nerves and the brain: D) Nervous Tissue 4. Describe five general characteristics of epithelial tissue: a. Protection (skin) b. Absorption (intestine) c. Secretion (glands) d. Filtration (kidney) e. Diffusion (lung and blood vessels) 6. What structural features do epithelia that provide for protection have in common? They have multiple layers to protect against friction and trauma 7. Cell-Surface Modification

Type(s) of epithelia with the modification

Function (include a specific organ)

Cilia

Hair-like projections on cell surface

Move in a wavelike manner to move substances along cell surface

Goblet Cells

Looks like glass with stems

Slimy coating that protects and lubricates surfaces In the intestines

Microvilli

Fingerlike extensions of plasma membrane

Function is absorption

10. What are three general characteristics of connective tissues? Protect, support, insulate, and bind together 13. Use the key to identify the connective tissues described below 1. Attaches bones to bones and muscles to bones D) dense regular connective tissue 2. Insulates against heat loss A) adipose connective tissue 3. Forms the fibrous joint capsule. C) dense irregular connective tissue 4. Makes up the intervertebral discs

G) fibrocartilage 5. Composes basement membranes; a soft packaging tissue with a jellylike matrix B) areolar connective tissue 6. Forms the larynx, the costal cartilages of the ribs, and the embryonic skeleton H) hyaline cartilage 7. Provides a flexible framework for the external ear E) elastic cartilage 8. Provides levers for muscles to act on I) 9. Forms the walls of large arteries F) 14. What two physiological characteristics are highly developed in neurons? Irritability and conductivity 17. Skeletal Muscle: D, E, I, H Cardiac Muscle: B, A, G, J, L Smooth Muscle: C, F, G, K 22. A. B. C. D. E. F. G. H. I. J. K. L.
