BIO-168 Module 2 Exam Review Questions and Answers
What are the 4 main types of tissues? - -1. Epithelial
2. Connective
3. Muscle
4. Nervous
-Which muscle tissue is composed of cells which are fusiform, uninucleated, nonstriated
and under involuntary control? - -Smooth
-A normal tissue response to injury that involves redness, swelling, heat, pain, and altered
functioning of the affected area is called - -Inflammation
-An aggregation of cells and extracellular materials which performs a discrete function is
known as a(n) - -Tissue
-What are the 3 germ layers? - -ectoderm, mesoderm, endoderm
-Where is the endoderm? - -Inner layer, forms the lining go the digestive tract and
derivatives
-Where is the mesoderm located? - -middle layer, forms tissues such as muscle, bone and
blood vessels
-Where is the ectoderm located? - -outer layer, forms the skin and neuroectoderm
-What is the structure of epithelial tissue? - --consists of almost of mainly cells
-has free, basal, and lateral surfaces
-specialized cell contacts
-avascular (lacks blood vessels)
- can regenerate
-Where is epithelial tissue found? - -body coverings, body linings, glandular tissue
-What is the basement membrane? - --it is extracellular and is formed by secretions of
both epithelium and connective tissue. Acellular "glue"
-Microvilli - -increase surface area for absorption
-Stereocilia - -elongated microvilli for sensation and absorption
-Cilia - -Move materials across the cell surface
-Types of Specialized Cell Connections - --Desmosomes
-Hemidesmosomes
