Levels of Organisation Flashcards
Cell Structure and Organisation
1
Q
What are the main features of cuboidal epithelium?
A
- One cell thick
- No blood vessels but may have nerve endings
- Sits on a basement membrane
- Often protective or secretory function
2
Q
What are the main features of Ciliated columnar epithelium?
A
- Elongated
- Sits on a basement membrane
- Columnar epithelial cells which guide substances through
- Lined with cilia
3
Q
What are the main features of Squamous epithelium?
A
- Sits on a basement membrane
- Flattened cells
4
Q
What are Epithelial Tissues?
A
Form the lining of all external and internal body surfaces.
5
Q
Where would you find Cuboidal Epithelial tissue in the body?
A
- Salivary glands
- Proximal convoluted tubule in nephron (kidney)
6
Q
Where would you find Ciliated Columnar Epithelium tissue in the body?
A
- Oviduct
- Trachea
7
Q
Where would you find Squamous Epithelium tissue in the body?
A
- Forms the walls of the alveoli
- Lines the renal capsule in the kidneys
8
Q
What are the main features of Skeletal muscle?
A
- Generates locomotion
- Bands of long cells or fibres which give powerful contraction
- They are voluntary muscles
- Striated
- They tire
- Long cells or fibres
9
Q
Where is the skeletal muscle found?
A
Attached to the bones
10
Q
What are the main features of Smooth muscle?
A
- Involuntary muscles
- Unstriated muscles
- Contract rhythmically
- Unlikely to tire
- Individual spindle- shaped cells
11
Q
Where is the Smooth muscle found?
A
- Skin
- Blood vessels
- Digestive/ respiratory tracts
12
Q
What are the main features of Cardiac muscle?
A
- Contract rhythmically without stimulation from nerves or hormones
- Striated
- Does not tire
- Hormones and nerves can modify contraction
13
Q
Where is cardiac muscle found?
A
The heart
14
Q
Describe connective tissue.
A
- Connects tissues that are separate
- Contains elastic and collagen fibres in an extracellular fluid or matrix
- Between fibres are adipocytes (fat storing cells) and cells of the immune system.
15
Q
Describe Nervous tissue.
A
- Connects the Central Nervous System to the rest of the body
- Composed of specialised cells
