Practice Test 2 Flashcards
3 systems reporting information to the brain to help with balance
Vision
Vestibular (ear crystals)
Proprioception
the main flexor muscle of the elbow
Brachioradialis
the scapular retractors
Rhomboids Major and Minor
Heather’s 3 keys to shoulder health
- Good Alignment/Posture
- Strong Scapular Stabilizers
- Strong Rotator Cuff
Clavicle
connects the upper limb to the trunk. from which the scapula and
free limb are SUSPENDED
the motion of the deltoid and a pose that uses all parts of the deltoid
Action: Anterior part- Flexes and internally rotates arm
Middle part- Abducts arm
Posterior part- Extends and Externally rotates arm
When all work together the arm abducts and the anterior posterior parts steady the arm. (Except the first 15 degrees, supraspinatus).
Warrior 2
supraspinatus
the first 15 degrees of arm abduction
Rotator Cuff
Protects and Stabilizes the Joint
The tonic contraction holding the large head of the humerus in the small shallow
glenoid cavity during arm movements
Supraspinatus
Infraspinatus
Teres Minor
Subscapularis
Collectively the prime function during all movements of
the shoulder joint is to hold the head of the humerus in
the glenoid cavity of the scapula.
Rotator Cuff Supraspinatus
Supraspinatus:
Initiates and assists deltoid in
abduction of the arm and acts with Rotator Cuff.
Rotator Cuff Infraspinatus
Infraspinatus:
Laterally (externally) rotate arm, holds
humeral head in glenoid cavity.
Rotator Cuff Teres Minor
Teres Minor: Laterally rotate arm (externally), holds
humeral head in glenoid cavity.
Rotator Cuff Subscapularis
Subscapularis: Medially (internally) rotates arm and
adducts it, holds humeral head in glenoid cavity.
Adductor Pollicis
Adducts the thumb
Are there muscles on top of the skull
yes
what joint the superficial muscles of the back move

Knee Flexors
Hamstrings: Bicep Femoris (back of the thigh towards the lateral side)
Semi Tendinous (middle back thigh)
Semi Membranous (medial back thigh)
Gracilis (outer edge of knee)
Sartorius
Gastrocnemius (calf muscles)
Plantaris (deep and right below the need and the posterior side)
Anterior Compartment Lower Leg:
Anterior Tibialis: Dorsiflexion, Inversion of Foot Extensor Hallucis Longus \: Extension of Great Toe, Dorsiflexion, Inversion Foot Peroneus Tertius \: Eversion of Foot, Dorsiflexion Extensor Digitorum \:Extension of toes, Dorsiflexion, Eversion of Foot ***All Anterior Compartment assists w/ Dorsi Flexion
Posterior Compartment
Superficial:
Gastrocnemius: Plantar Flexion
Soleus (bent knee): Plantar Flexion
Plantaris: Plantar Flexion
ALL posterior compartment assist w/ Plantar
Flexion
Flexor Hallucis Longus: Flex Great Toe,
Inversion Foot, Plantar Flexion
Flexor Digitorum Longus: Flex toes 2-5,
Inversion Foot, Plantar Flexion
Posterior Tibialis: Inversion Foot, Plantar Flexion
Special—-popliteus: Does not Plantar Flex, it
unlocks (rotates) knee from full extension.
what musculoskeletal component provides the
major stability for the knee
Ligaments
Muscles of the hamstrings
Bicep Femoris
Semi Tendinous
Semi Membranous
the primary muscle that produces hip flexion
Iliopsoas
Quadriceps how many muscles and where they begin and end
pelvis to tibia Quadriceps 4 Rectus Femoris Vastus Lateralis Vastus Medialis Vastus Intermedius (deep to rectus femoris)
Hamstrings how many muscles and where they begin and end
begin at pelvis end at front of the tibia
3
Bicep Femoris
Semi Tendinous
Semi MembranousThe hamstrings attach to
the tibia
Distal tibia and distal fibula are
malleolus which make the ankle bones
What action the gastrocnemius and soleus produce together
Plantar Flexion
Hallucis
Muscle that abducts and flexes big toe
Pollicis
Muscle that abducts and flexes the thumb
The action of the quadriceps
Hip Flexion (Rectus Femoris) Knee Extensors
The action of the hamstrings
Hip extension
Knee Flexors
action of the Anterior Tibialis
Dorsiflexion, Inversion of Foot
Actions of the pectoralis major
Adducts and medially (internally) rotates
humerus, draws scapula anterior and inferior.
Action of the triceps
Extends the Elbow. Long Head steadies head of abducted humerus. Aids
in extension and adduction of the shoulder.
