4 Characteristics of Muscle tissue:
|
1.) Excitability
2.) Contractility 3.) Extensibility 4.) Elasticity |
|
|
3 functions of muscular tissue:
|
1.) Motion: movement of body parts and materials
2.) Stability: maintaining a stable posture and joint stability 3.) Heat: skeletal muscles produces 85% of body heat (through muscle contraction) |
|
|
Muscle tissue differ in terms of:
|
- location
- histology - control |
|
|
List the types of muscle tissue:
|
1.) Skeletal
2.) Cardiac 3.) Smooth |
|
|
Skeletal muscle:
|
- Attached to skeleton
- striated - voluntary - multiple nuclei |
|
|
Cardiac muscle:
|
- in the heart
- striated - involuntary - branched |
|
|
Smooth muscle:
|
- in organs
- not striated - visceral - involuntary |
|
|
"muscle cell" can also be referred to as _______
|
muscle fibers
|
|
|
Smooth muscles are also found in:
|
skin of erector pili
|
|
|
Lable the skeletal muscle anatomy starting from the superficial layer:
|
1.) Integument
- Epidermis - Dermis - Hypodermis 2.) Deep Fascia 3.) Muscles 4.) Deep Fasica 5.) Bone |
|
|
Connective Tissue Component of skeletal muscles:
|
1.) Endomysium
2.) Perimysium 3.) Epimysium 4.) Attachments |
|
|
Endomysium
|
Endomysium is the innermost connective tissue sheath that wraps around each individual muscle fiber
|
|
|
Perimysium
|
Perimysium is a connective tissue sheath that wraps around a muscle fascicle
|
|
|
Epimysium
|
Epimysium is a connective tissue sheath that surrounds (wraps around) the entire msucle
|
|
|
aponeurosis:
|
- a broad flat tendon
- Endomysium, perimysium, and epimysium are continuous with the attachments of the muscle to the bone |
