A&P 1 L 5 Flashcards
Raising a part (shrugging the shoulders)
Elevation
Lowering a part (drooping the shoulders)
Depression
Moving a part backward (pulling the chin backward)
Retraction
Moving a part forward (thrusting the chin forward)
Protraction
Turning the foot so the sole faces medially
Inversion
Turning the foot so the sole faces laterally
Eversion
Turning the hand so the palm is downward or facing posteriorly (in anatomical position)
Pronation
Turning the hand so the palm is upward or facing anteriorly (in anatomical position)
Supination
Moving a part so that its end follows a circular path (moving the finger in a circular motion without moving the hand
Circumduction
Moving a part around an axis (twisting the head from side to side).
Rotation
Moving a part toward the midline (returning the upper limb from the horizontal position to the side of the body)
Adduction
Moving a part away from the midline (lifting the upper limb horizontally to form a right angle with the side of the body)
Abduction
Bending the foot at the ankle toward the sole (bending the foot downward)
Plantar flexion
Bending the foot at the ankle toward the shin (bending the foot upward)
Dorsiflexion
Excess extension of the parts at a joint, beyond the anatomical position (bending the head back beyond the upright position)
Hyperextension
Straightening parts at a joint so that the angle between them increases and the parts move farther apart (straightening the lower limb at the knee)
Extension
Bending parts at a joint so that the angle between them decreases and the parts come closer together (bending lower limb at the knee)
Flexion
Muscle primarily responsible for a particular movement
Prime mover
What muscle helps the prime mover
Synergistic muscles
What muscle resist the prime mover and stabilizes the muscle
Antagonist
Joint capsule of a synovial joint is called a
Bursa
What is the fluid that serves as the best lubricant
Synovial fluid
Moveable end of a joint
Insertion
The non moveable end is known as? Also known as?
Origin/fixed
2+ bones come together to form a joint
Articulation
Muscles are found in
Groups
What type of tissue is found around synovial joints
C.T
Binds muscle to bone
Tendons
When fascia comes together it forms what
Tendons
What separates individual muscles into groups
Fascis
What muscle surrounds the muscle to form a bundle
Aponeuroses
What divides the muscle inside the muscle
Paramycium
The expanded pouch on the sarcoplasmic reticulum (SR) is called a
Cristernae
What allows the nervous impulses to enter a muscle cell
T. Tubes (transverse tubules)
