Vert Bio- Exam 2 Flashcards
Levator
elevate; moves body to superior position
Depressor
Lowers bone in vertical plane
Extension
To open, or unfold. increase angle of a joint
Hyperextension
Increase angle of joint beyond normal
Flexion
Fold or decrease angle between bones/body regions
Lateral Flexion
Trunk/neck: movement in frontal plane away from median. Side bending.
Adduction
Pull toward midline
Abduction
Pull away from midline
Lateral Rotation
Movement in transverse plane that takes part of body outward
Medial Rotation
Movement in transverse plane. Takes part of body inward
Pronate
Turn ventral side down
Supinate
Turn ventral side up
Constrict
Contract circular muscle
Dilate
Relax circular muscle
Protract
Drag forward in horizontal plane
Retract
Drag back in horizontal plane
Red muscle fibers
aerobic. High myoglobin
White muscle fibers
Larger. Strong. Anaerobic
Hyobranchial muscles
