(transverse) Example: Radioulnar
Ball and socket joint - ANSWER Most mobile of joints; moves in all three planes of
motion (shoulder)
Transverse abdominis - ANSWER What muscle is this?
Isolated function of the Transverse abdominis - ANSWER Increases intra-abdominal
pressure
Supports the abdominal viscera
Integrated function of the transverse abdominis - ANSWER Isometrically stabilizes the
LPHC
Diaphragm (muscle) - ANSWER What muscle is this?
Isolated function of the diaphragm muscle - ANSWER Concentrically pulls the central
tendon inferiorly, increasing the volume in the thoracic cavity
,Integrated function of the diaphragm muscle - ANSWER Stabilizes the LPHC
Quadratus lumborum - ANSWER What muscle is this?
Isolated function of the quadratus lumborum muscle - ANSWER Spinal lateral flexion
Integrated function of the quadratus lumborum muscle - ANSWER Eccentrically
decelerates contralateral lateral spine flexion
Isometrically stabilizes the LPHC
Multifidus - ANSWER What muscle is this?
Isolated function of the multifidus muscle - ANSWER Concentrically accelerates spinal
extension and contralateral rotation
Integrated function of the multifidus muscle - ANSWER Eccentrically decelerates spinal
flexion and rotation
Isometrically stabilizes the spine
Latissimus doris - ANSWER What muscle is this?
Optimal dynamic posture at the five kinetic chain checkpoint - ANSWER Feet- hip to
shoulder width apart; pointed straight ahead;
Knees- soft and extended; in line with 2nd and 3rd toes
LPHC- neutral; abs and glutes engaged.
Shoulders- back and down; no thoracic rounding.
Head/neck- cervical spine neutral
Atria - ANSWER Superior chambers; receive blood from outside the heart
Right Atrium - ANSWER Gathers deoxygenated blood from body
Sinoatrial (SA) - ANSWER Located in right atrium; receives signal to contract;
"pacemaker for the heart". Initiates the electrical impulses that determine the heart rate
Stroke Volume (SV) - ANSWER Amount of blood pumped with each contraction
What are the functions of blood? - ANSWER transportation, regulation, protection
Anterior - ANSWER Front of body
,Posterior - ANSWER back of body
Superior - ANSWER Above point of reference
Inferior - ANSWER Below point of reference
Proximal - ANSWER Closer to the center of the body.
Distal - ANSWER Farthest from the center of the body
Medial - ANSWER Toward the midline of the body
Lateral - ANSWER Further from midline of the body
Pronation - ANSWER Tri-planar movement (eversion, dorsiflexion, and abduction of
feet)
Sagittal - ANSWER Divides body into left and right halves; forward-backward
movement
Flexion - ANSWER bending of joints; decreases relative angle
Extension - ANSWER Straightening of joints; increases relative angle.
Plantar flexion - ANSWER extension at ankle (pointing toes)
Dorsiflexion - ANSWER Flexion at ankle (backward bending at ankle)
Frontal Plane - ANSWER Divides the body into front and back halves; side to side
movement.
Abduction - ANSWER movement away from midline
Adduction - ANSWER Movement towards the midline
Inversion - ANSWER Bottom of foot rotates medially
Eversion - ANSWER bottom of foot rotates laterally
, Eccentric - ANSWER Produces tension while lengthening in order to resist or control an
external force (ex: Bicep curl)
Horizontal abduction - ANSWER lateral-rotational movement away from midline
Horizontal adduction - ANSWER Medial-rotational movement toward the midline
Internal rotation - ANSWER inward rotation of limbs
External rotation - ANSWER outward rotation of limbs
Talk test - ANSWER Self-evaluation of intensity associated with ability to talk while
exercising.
Supination - ANSWER Tri-planar movement (inversion. plantar flexion, and adduction
of feet)
Length-tension relationship - ANSWER length at which muscle can create most
tension; too short or too long = reduced force production
Force-Couple - ANSWER muscles moving together to produce movement
Reciprocal (opposite) inhibition - ANSWER The muscles on one side of a joint relax to
allow the muscles on the other side to contract. (ex: triceps relax while biceps contract.)
Alarm - ANSWER Initial response to exercise; 2-3 weeks.
general adpatation syndrome - ANSWER How the body response and adapts to stress;
alarm, adaption, and exhaustion.
Adaption - ANSWER body adapts to stimuli, progressive improvement, 4-12 weeks.
Exhaustion - ANSWER Body no longer tolerates demands of training; adaptions may
halt; overtraining syndrome risk increases.
Mechanical Specificity - ANSWER Weight and movements placed on the body .
Metabolic Specificity - ANSWER Energy demand placed on body
Concentric - ANSWER produces tension while shortening to overcome external
