Arteries
Veins
2 body part movements that are exceptions regarding sagittal plane movements
Thumb flexion and ankle (dorsiflexion and plantar flexion)
Bone formation in soft tissue (not normally present) can lead to Hemorrhagic calcification

Cardiac Muscle
-location
-Appearance
-Types of Activity
- stimulation
-Muscle of heart and adjacent portions of greater vessels
-branching shorter fibers with transverse striations
-strong, quick, continuous contraction [pumps blood to heart]
- Involuntary by Autonomic NS
small venules can grow to create a different path to allow circulation is called
collateral circulation
Scapula does ____ and _____ , _____ and ______
elevation and depression, protraction and retraction
Loss of blood supply to bone

abduction and adduction
rotation
Name 3 functions of bone
ANY 3
•Living, hard, connective tissue
•Protects and supports body and cavities
•Basis for movement
•Salt Storage
•Produces new blood cells
Name all the types of synovial joints (6) and what movement they do
-ball and socket [Permits movement in several directions]
-hinge [Flexion and extension only]
-saddle [Concave and convex where bones meet]
-condylar [Wider range into flexion and extension, reduced range in other directions]
-pivot [allows rotation]
-plane [Permit gliding]
Define
-isometric
-isotonic
-Concentric
-Eccentric
•Isometric: Length stays the same resulting in tension, but no movement
•Isotonic: Length change to produce movement
•Concentric: Movement due to muscle shortening
•Eccentric: Movement due to muscle lengthening
Muscle contraction aids in returning blood to the heart with valves preventing back flow is called
• Musculovenous pump
