Aponeurosis

Back 9

Flat broad bands.Aponeuroses (plural of aponeurosis: απο, "away" or "of", and νευρον, "sinew") are layers of flat broad tendons.

Front 10

Deep Fascia

Back 10

Deep fascia (or "investing fascia") is a layer of fascia which can surround individual muscles, and divide groups of muscles into compartments.

This is the dense fibrous connective tissue that interpenetrates and surrounds the muscles, bones, nerves and blood vessels of the body. It provides connection and communication in the form of aponeuroses, ligaments, tendons, retinacula, joint capsules, and septa. The deep fasciae envelop all bone (periosteum and endosteum); cartilage (perichondrium), and blood vessels (tunica externa) and become specialized in muscles (epimysium, perimysium, and endomysium) and nerves (epineurium, perineurium, and endoneurium).

Front 11

Sarcomere

Back 11

Actin filaments found in thin filabments and myosin filaments are found in thick filaments. The actin and myosin filaments are organized in repeating units called sarcomeres.

Front 12

H Zone

Back 12

Part of the A band H band is thick filaments only and the zone of overlap thick and thin filaments.

Front 13

A Band

Back 13

Area containg thick filaments. Comprised of the A and M bands

Front 14

I Band

Back 14

Contains only thin filaments . Region between A and Z bands.

Front 15

M Line

Back 15

Thick filament lie in the coneter of the sarcomere linked by proteins of the M line.

Front 16

Z Line

Back 16

Thin filamens at either ind of the sarcomere attached to interconnecting proteins that make up the Z lines. Z lines delineate the ends of the sarcomere.

Front 17

Myofilaments

Back 17

Make up proteins of actin and myosin. Myosin part found in thick filaments.

Front 18

Crossbridges

Back 18

On the thick heads of the myofilaments.

Front 19

Thin Filament

Back 19

Each thin fialment consits of a twisted strand 5-6nm in diamer and 1 um in length. Actin

Front 20

Troponin

Back 20

Complex of three subunits. Prevents Anti myosin in the resting muscle

Front 21

Flexion

Back 21

Movement in the anterior-posterior plane that reduces the angle between articlating elements.

Front 22

Extension

Back 22

Occurs in the same plane but it incresases the angle between articlulating elements. When you bring your head toward your chest you flex the intervetebral articlations of the neck. When you bend to touch your toes.

Front 23

Adduction

Back 23

Wrist moves the heel of the hand toward the body.

Front 24

Abduction

Back 24

Wrist moves the heel of the hand away from the body.

Front 25

Medial

Back 25

Internal rotation arm toward stomach

Front 26

Lateral rotation

Back 26

Arm rotation away from the stomach this is an external rotation

Front 27

Eversion

Back 27

A twisting motion of the foot that turn the sole outward.

Front 28

Inversion

Back 28

A twisting motion of the foot that turn the sole inward.

Front 29

Promation

Back 29

Pronation is a rotational movement of the forearm at the radioulnar joint, or of the foot at the subtalar and talocalcaneonavicular joints.

Front 30

Supination

Back 30

Supination is a position of either the forearm or foot; in the forearm when the palm faces anteriorly, or faces up (when the arms are unbent and at the sides).

Front 31

Plantar Flexion

Back 31

Plantarflexion (or plantar flexion) is the movement which increases the approximate 90 degree angle between the front part of the foot and the shin, as when depressing an automobile pedal

Front 32

Dorsiflexion

Back 32

Dorsiflexion is the movement which decreases the angle between the dorsum (superior surface) of the foot and the leg, so that the toes are brought closer to the shin.

Front 33

Lateralflexion

Back 33

When the vertebral column bends to the side.

Front 34

Elevation

Back 34

When you shrug your shoulders

Front 35

Depression

Back 35

Closing your mouth

Front 36

Protraction

Back 36

Entails moving a part of the body anteriorly in the horizontal plane.

Front 37

Retraction

Back 37

Retraction in the reverse movement.

Front 38

Sarcoplasmic Reticulum

Back 38

The sarcoplasmic reticulum (SR), from the Greek sarx, ("flesh"), is a special type of smooth ER found in smooth and striated muscle. The only structural difference between this organelle and the SER is the medley of proteins they have, both bound to their membranes and drifting within the confines of their lumens. This fundamental difference is indicative of their functions: the SER synthesizes molecules while the SR stores and pumps calcium ions. The SR contains large stores of calcium, which it sequesters and then releases when the muscle cell is stimulated.

Front 39

Calcium Ions

Back 39

Calcium ions are important mediators of a great variety of cellular activities, including the passing of information between neurons and down a neuron. Neurotransmiters.
