5 functions of Skeletal System
5. Blood Cell Production
Epimysium in Fasicle
Fibrous sheath around an entire skeletal musle
Perimysium in Fasicle
Sheath of connective tissue surrounding a bundle of muscle fibers
Endomysium in Fascicle
Encloses or wraps around each mm fiber (inside)
H-Zone (M-line) aka "Soda can"
Actin -Thin filaments Myosin -Thick filaments "heads=ohers." Split ATP to generate power for mm contraction
Where the mm shortens. Ex: bending knee, elbow
Where the mm neither lengthens or shortens.
Ex: Pushing over a wall
The muscle enlongates (gets bigger)
The muscle shortens
Longest part of bone
2 types of bone
Compact - solid Cancellous "spongy"- small marrow filled.
Healing of a Fracture
1.Blood vessels are ruptured, swelling occurs 2.Fibrocartilage splints the bone 3.Bony callus is formed 4.Bone remodeling occurs
"Rib cage" Made up of 3 parts
2. Ribs-connects 1 + 3
