Anatomy Yoga Flashcards
Osteoblasts
Bone forming cells
brahma
Osteocytes
Bone cells that have matured and are maintaining form
Vishnu
Osteoclasts
Bone cells that break down and dissolve bone
Wolff’s law
Piezoelectric effect
Calcium is laid down in response to stress
Physical stress increases bone density
Piezoelectric effect
Pressure placed on a tissue a slight electrical charge results blocking osteoclasts and allowing the osteoblasts to build up bone tissue
Bones
206 bones in the body
Axial skeleton
Ribcage sternim vertebral column skull mandible cervical thoracic and lumbar spine sacrum coccyx

Bony pelvis hip joint Femur knee joint patella fibula tibia ankle tarsals meta tarsals phalanges of the foot
Sthira Sukham Asanam
Steady, ease filled, meditation posture
Anatomy and kinesiology
Two essential characteristics of posture are stability and space
Isotonic
Concentric a muscle shortens as it contracts
Eccentric a muscular contraction that lengthens
Isometric
Muscle attempts to contract but no movement occurs
Stretch
The ability of a tissue to lengthen without damage
Contactility
The ability of a tissue to shorten unique to muscle tissue
Elasticity
The ability of a tissue to return to its former shape after it has been stretched
Tensegrity
The ability of a tissue to withstand a pulling force without damage
Plasticity
The ability of a tissue to have its shape molded and altered and will hold its shape unique to connective tissue
Weight bearing
The ability of a tissue to bear a compressive force or weight from above it without damage
Creep
The gradual shape change of a tissue from sustained and applied pressure
Thixotrophy
The ability of a tissue to change from a more rigid gel state to a softer Sol state allowing for more freedom in movement and for greater ability of circulation
Agonist
A muscle of force that can do the action in question.
A mover muscle always shortens when the movement occurs through contracentrically contracting except in the case of outside forces of gravity or assists
Antagonist
A muscle of force that can do the opposite of the action in question
Eccentrically contracting or relaxing and allowing movement in question to occur
Stabilizer
A muscle force that can stop and unwanted action at the fixed attachment of the muscle that is working
Neutralizer
A muscle force that can stop an unwanted action at the fixed attachment of the muscle that is working
Support muscle
A muscle that can hold another part of the body in a stable position while the action is occurring
Synergist
A muscle that works with the action in question
Static stretch
Held on a comfortable but challenging position for a short period of time
Dynamic stretch
A stretch performed by moving through a challenging but comfortable range of motion repeatedly
Passive stretching
Passivusing am outside assistant to help achieve a stretch
