Body Movement Terminology
circumduction: proximal end of limb is stationary and distal end moves in circle
Dorsiflexion: surface of foot towards shin
Adduction: movement of limb toward the midline
Planter Flextion: pointing toe
Inversion: turn sole of foot medially
Rotation: movement of bone around longitudinal axis
Eversion: turn sold of foot laterally
Extension: movement that increases angle of joint; hyperextention extends beyond 180
pronation: forearm rotates medially, palm faces posteriorly
Flexion: movement that decreases angle of joint
opposition: movement of thumb to touch tips of other fingers
supination: foream rotates laterally, palm faces anteriorly
Major Function
posture: stabilizing joints, body posture, and regulate organ volume
Movement/motion: body position and movement within body
thermogenesis: heat production
Three Types of Muscles Tissues and Function
Smooth muscle: involuntary, cannot consciously control it and spindle shaped with single central nucleus and has no striations and appearns smooth also controls movements inside internal organs
Cardiac muscle: involuntary, cannot consciously control it and it long, cylindrical, branched,and has single central nucleus then forms the heart wall
Skeletal: long, cylindrical, parallel, and multinucleate; striated; voluntary; attached by tendons to bones
Name of muscles
Sartorius : thigh
Adductor: long is: thigh
Iliopsoas: hip muscle
Extensor digitorum: back side of forearm
Flexor carping ulnaris: ulnar side of foream
Extensor carpio radialis : muscle under elbow and above wrist.
Rectus abdominis, around the abdomen
Flexor carping radialis, anterior part of forearm
Latissimus dorsi: largest muscle on the mid-back
Brachioradialls, forearm
Trees major: upper side of the upper arm
Tricep brachii: muscle placated back of humorous
Infraspinatus, back of the shoulder
Bicep brachii, anterior of upper arm
External oblique, outer layer/surface of the abdomen
Serratis anterior: 1st to 8th ribs of muscle at the side of the upper chest
Sternocleidomastoid . Around sternum and clavical
Pectoralis major: large muscle on upper chest
Trapezoids. Upper part of back and lower part of neck
Deltoid: muscle in the upper part of the arm
Sliding filament theory
Myosin head attaches to actin forming a cross bridge
Myosin head moves toward M line actin filaments passes myosin
Calcium binds acting creating myosin binding sites
ATP is released so myosin heads are released from actin
Nerve impulses that travel down sarcolemma and into t tubes causing sarcoplamic reticulum to release calcuim
Z lines get closer, sarcmeres get ahorter
Structure and organization levels of the skeleton muscle
Tendon
Muscular fibers
Bone
Sarcomere
Thin and thick filaments
Abduction: movement of limb away from mid line
