Production of sperm and gametes

18
Q

Function of nervous system

A

Regulate body activities through nerve impulses

19
Q

Function of endocrine system

A

Regulate body activities through releasing hormones

20
Q

Function of lymphatic and immune system

A

Defence

21
Q

Function of respiratory system

A

Transport of oxygen and carbon dioxide between blood and air

22
Q

Function of urinary system

A

Urine production

23
Q

Key function of epithelial tissue

A

Form selective barriers, secretory, protection

24
Q

Where are tight junctions located

A

Near the apical surface

25
Q

Purpose of tight junctions

A

Prevent migration of proteins between apical and basal surfaces. Form a seal (are electrically tight), provide polarity to the cell

26
Q

Adherans junction location

A

Near the apical surface, but below tight junctions

27
Q

Purpose of adherans junctions

A

Provide structure and strength to the cell, a link from the cytoplasm of one cell to the cytoplasm of another

28
Q

Location of desmosome junction

A

Towards the bottom of the cell, lowest of all lateral junctions

29
Q

Purpose of desmosome junctions

A

Link the intermediate filaments of one cell to another, important for structural integrity,

30
Q

Location of Gap junctions

A

Below adherans junction, above desmosome junction

31
Q

Purpose of gap junctions

A

Involved in communication, ions can travel through gap junctions, important communication network

32
Q

Location of hemidesmosome junctions

A

Located on the basal surface of the cell, attached to the basement membrane

33
Q

Purpose of hemidesmosome junctions

A

To connect the cell to the basement membrane so it cannot slide around
