muscle tissue

Question 1

Explain basic things about muscle

Answer 1

Low/moderate mitotic rate
Allows/controls movement of the body
Rich blood supply needed providing sufficient oxygen calcium nutrients and removing waste products

Question 2

What are the three types of muscle tissue?

Answer 2

Cardiac, skeletal, smooth

Question 3

Where are all the different muscle tissues located?

Answer 3

Cardiac – heart
Skeletal – body
Smooth – digestive system

Question 4

Explain if each muscle tissue is involuntary or voluntary

Answer 4

Cardiac – involuntary control
Skeletal- voluntary control
Smooth – involuntary control

Question 5

Explain about cardiac muscle tissue

Answer 5

involuntary control
Only located in the heart wall
Each fibre (Cell) has one nucleus and one or more branches
The intercalated discs appear darker
When the heart contracts a wave comes cell to cell across the intercalated disks

Question 6

Explain about skeletal muscle tissue

Answer 6

voluntary control
Move bones of the skeleton

The fibres are cylindrical
and Multiple nuclei
and 35 cm long

Skeletal muscle contraction is stimulated by motor nerve impulses from the brain or the spinal cord and end at a neuromuscular junction

Question 7

Explain about smooth muscle tissue

Answer 7

involuntary control
Intrinsic ability has its own contraction innovated by the autonomic nervous system
Autonomic nerve impulses, some hormones and local metabolites regulate contraction,

Rich in mitochondria which make them fuel slow and sustained activity
Are present in hollow organs

Question 8

How does skeletal muscle tissue look like

Answer 8

The fibres are cylindrical, so you can tell from the image, more big and less dots

Question 9

How does Smooth muscle tissue look like

Answer 9

Very condensed and squished together and a lot of dots

Question 10

How does cardiac muscle tissue look like?

Answer 10

each line isn’t straight and some of them connect to each other
