Flashcards in Lab 2: tissues Deck (15):
1

connective tissue consists of
4 types of tissue

cells and extracellular material
connective, epithelial, muscle, and nervous

2

fibroblasts:

cells of connective tissue responsible for synthesis and maintenance of extracellular material.

3

ground substances

amorphous material that binds grounds substances, forming a medium for the passage of materials throughout the connective tissues and for exchange of metabolites with circulatory system

4

3 main fibre types

collagen, the most abundant protein in the animal body
elastin, rubber-like material arranged as discontinuous sheets
structural glycoproteins, which are associated with the cell surface membranes

5

Blood

a major type of connective tissue, made up of plasma, rbc (erythrocytes), wbc (leukocytes), and platelets (thrombocytes)

6

hematopoiesis

blood cell and platelet generation in bone marrow

7

epithelial tissue

lines all body surfaces, cavities, and tubes, functions as interfaces between compartments

8

classification of epithelium

1. number of cell layers: simple or steraified
2. shape of cells: squamous, columnar, etc
3. presence of surface specializations like cilia or keratin

9

types of muscle tissue

skeletal, smooth, and cardiac

10

skeletal muscle/voluntary muscle

used for movement of skeleton, made of contractile proteins and striated muscle

11

smooth muscle/visceral muscle

muscular component of blood vessels, digestive tract, uterus, and urinary bladder, among other viscera
control automatically and through hormone, thus involuntary

12

cardiac muscle

striated and mono-nucleated

13

intercalated disks

responsible for force transmission of contractions between cells and support the spread of APs

14

Nervous tissue

neurons made of sensory receptors, conducting pathways, and sites of integration and analysis

15

3 types of cartilage

elastic, hyaline, and fibrocartilage
