Q

What is the structure of a stratified epithelia?

A

Some cells stack on top of other cells and the upper layers of the cells don’t touch the basement membrane

Q

Function of the endoderm?

A

inner layer - Produces mucous membrane of respiratory tract, thyroid gland, secretory parts of pancreas

17
Q

Function of the mesoderm?

A

middle layer - Gives rise to connective and muscle tissue

18
Q

What’s the function of exocrine glands?

A

Secretes products into ducts

19
Q

Function of the endocrine glands

A

Secretes hormones into blood

20
Q

What is the most widespread, and the most varied of all the tissues?

A

Connective tissue

21
Q

What is the role of neurons?

A

Conduct nervous impulses

22
Q

What is the role of neuroglia?

A

Protect and assist neurons

23
Q

What is the soma of the neuron, and what does it contain?

A

Large cell body – contains the nucleus and the organelles

24
Q

Where are the dendrites found, and what is their role?

A

Multiple extend from the soma -Receive impulses from other cells, which they then transmit to the soma

25
Where is the axon found, and what is the role of the axon?
Neuron contains a single, long nerve fibre - axon - which transmits signals to other cells
26
What is the key component of the extracellular matrix of connective tissue?
The framework into which the cells of tissue are embedded
27
What type of tissue lies underneath almost all epithelia and connects tissues and organs together?
Areolar
28
*What are the basic classifications of connective tissue?
Fibrous connective tissue, Cartilage, bone, and blood
29
Fibrous connective tissue’s maybe either
Dense or loose
30
Loose connective tissues are further Divided as being
Areolar tissue, adipose tissue, reticular issue
