Lesson # 7 Muscle Rules Flashcards
Type of Muscle that is Striated (meaning light dark appearance) because of the proteins inside)
Aka - Muscle Fibers
Skeletal Muscle

Skeletal Muscle
Type of Muscle?
No Satiations
Prominent feature is the long dark nuclei ( the large spots in the tissue )
Cells look “ Flat & Wavy “ squished together going one direction.
Smooth Muscle
Type of Muscle?
No Satiations
Prominent feature is the long dark nuclei ( the large spots in the tissue )
Cells look “ Flat & Wavy “ squished together going one direction.
Smooth Muscle Tissue

Smooth Muscle Tissue
Type of Muscle?
Has Striations throughout the cells with intercalated discs found between the cells
- intercalated disc anchors the cells together
They are highlighted in each box in the image
The third image highlighted shows the shape of the cardiac muscle cells are different then the shape of the other cell types meaning they are split in multiple directions looking like the letter V
Sometimes you can see Adipose tissue on the sides
Cardiac Muscle

What part of the skeletal muscle is this model? (Looks like spider webs )
Function: smooth reticulum stores calcium in a resting muscle
Smooth reticulum
What part of the skeletal muscle is on this mode?
Located between the 2 z disc
Sarcomere
What part of the skeletal muscle is this?
T tubules
What part of the skeletal model is this
It generates a nerve impulse to the T tubules to contact
Axon
What part of the skeletal muscle fiber model is this
Nucleus of the skeletal muscle cell
What are these in the skeletal muscle tissue ( red )
Mitochondria
Rule # 4 muscles are named based on the direction of their giver muscles
What does rectus ( aka six-pack )
mean on direction for muscle fibers
Parallel
Example: rectus abdominis
Rule # 4 muscles are named based on the direction of their muscles
Transversus means what direction
Perpendicular to a bone or body region
Example:
transverseus abdominis
Rule # 4 muscles are named based on the direction of their muscles
Oblique means __________ ( to a bone or body region )
At an angle
Example: external obliques
Rule # 6 - some muscles are based on the location of their attachment
What are the three places sternocleidoma muscles attaches to?
Sterno = muscle attaches to sternum
Cleido = muscle attaches to the clavicle
Mastoid = muscle attaches to a bone marking called mastoid process.
Sternocleidoma
