Muscle Tissue💪 (incomplete) Flashcards
What % of our body is muscle?
40-50%
How are muscle tissues specialised?
By producing movement by contraction
What are the three types of muscle Tissue?
-SKELETAL
-CARDIAC
-SMOOTH
What muscle tissue facilitates movement of the
a)Body
b)Blood
c)Gases, fluids and solids through our visceral or organs
a) Skeletal
b)Cardiac
c) Smooth
What is voluntary control of muscle tissues mediated by?
somatic motor system via motor neurones
What are motor neurones?
Motor neurones are neurones that can send signals from our brain to our muscles, telling them to contract
What is involuntary control of muscle tissue mediated by?
Autonomic Nervous System
What is the autonomic NS, and what does it control
Control system that acts unconsciously i.e. regulates functions like;
-Heart Rate
-Breathing
-Digestion
All of which involve muscle movement
What is the structure and control of each muscle type?
Muscle Type Control Structure
Skeletal somatic NS Striated
Cardiac autonomic NS Started
Smooth autonomic NS Non-striated
What do striated muscle tissues look like?
Have a striped or banded appearance
What do non-striated muscle tissues look like?
Do not have striped appearance
The striated structure of skeletal muscle is intimately related to what?
The function of this tissue
Where is cardiac muscle found and what is its function?
-Found only in the walls of our heart
-To pump blood around the body
What features does cardiac muscle tissue share with;
a) Smooth Muscle Tissue
b)Skeletal Muscle Tissue
a) Under Involuntary Control by Autonomic Nervous
System
b) Striated Appearance
Why is smooth muscle named as ‘smooth muscle’
Because it doesn’t have this striped appearance and appears smooth shape with tapered ends.
