tissues of the body Flashcards
1
Q
tissues
A
a group of cells that are similar in structure and work together to carry out a particular task
2
Q
what are the 4 body tissues
A
epithelial, connective, muscle, nervous
3
Q
epithelial tissue structure
A
- cells are very closely joined together
- vary in shape: thin + flat, cylindrical, cube
- covering/lining tissue
4
Q
eg of epithelial tissue
A
- intestines
- outer layer of the skin
- inner lining of the heart
- outer lining of the lungs
5
Q
connective tissue structure
A
- helps hold all body parts together
- cells not close together!
- separate by matrix (not cells)
6
Q
eg of connective tissue
A
- bones
- blood
- cartlidge
- tendons
- ligaments
- adipose (fat storage)
7
Q
nervous tissue structure
A
- made up of neurons
- messages travel around the body
8
Q
eg of nervous tissue
A
-brain
-spinal cord
-nerves
9
Q
skeletal muscular tissue structure
A
- attached to the bones
- voluntary control
- striations
- multiple nuclei
- cylindrical
10
Q
eg of skeletal muscle tissue
A
-quads
-biceps
11
Q
smooth muscular tissue structure
A
- no striations
-involuntary
-tapered edges
12
Q
eg of smooth muscle tissue
A
- wall of the stomach and intestines
- blood vessels
- iris
-uterus
13
Q
cardiac muscular tissue structure
A
- makes up most of the heart
- contracts = pumps blood
- branching cells
14
Q
eg cardiac muscular tissue
A
the heart
