What are the 4 attachments for muscles
Tendinous, aponeurotic, fleshy, raphe
What is a tendinous attachment
Fibrous tissue attach muscle fibres to bone- looks like a cord and silvery
What is an aponeurotic attachment and where is it generally located
Located at the abdominals, fibrous tissue attaching muscle fibres to bone- looks like a sheet is silvery dull e.g palmar aponeurosis
What is a fleshy attachment
Muscle fibre attached directly to the bone via epimysium e.g pec major to clavicle head
What is a raphe attachment
Muscles attaching directly to another muscle e.g under the neck
Name the four parallel muscle types and an example for each
Strap: e.g anterior thigh (satorius)
Fusiform: biceps brachii
Flat: pronator quadratus
Radiate: pec major
name the 3 types of pennate muscles and give an ex for each
Unipennate: extensor digitorum
bipennate: rectus femoris
multipennate: deltoid
Name two types of circular muscles
orbicularis oculi & oris, eyes and mouth respec.
What are the actions of the rotator cuff muscles and location
Subscapularis: subscapular fossa - medial rotation
supraspinatus: supraspinous fossa
infraspinatus fossa:
teres minor: lateral border of scapula
SIT: lateral rotation of humerus
What are the muscles moving humerus anteriorly; 3- action and location
Hint: P.M, D, B
pec major; sternum & clavicular head into intertubercular groove– flexion/ adduction/ medial rotation
deltoid anterior- flexion, abduction
biceps brachii; flexion
- long head (intertubercular groove)
- short head (coracoid process)
Location of coracobrachialis and action
attach at coracoid process and shaft of humerus,
- flexion and adduction
Posterior muscles of humerus actions-4
hint: D, L, T, T
deltoid (post): external rotation, extension
lats: adduction, extension, medial rotation
teres major: adduction, extension
triceps: extension
action of middle deltoid
abduction
Muscles moving scapular- anterior-2
hint: P.M, S.A
pec minor: protraction, medial rotation
serratus anterior: superior/inferior angle of scapula + medial border
- upward rotation, protraction
Posterior muscles-3
Hint: T, R, L.S
trapezius: upwards rotation/ lateral
- upper- elevation
- middle- retraction
-lower- depression
rhomboid major/minor: spinous process- retraction
levator scapular: cervical vertebrae to scapular spine: elevation
Muscles of the elbow- actions-5
biceps brachii: pronation
brachialis: elbow flexion, pronation
brachioradialis: flexion
pronator teres: pronation/ flexion
pronator quadratus: pronation
posterior muscles of the elbow region- actions-3
hint: T.B, A, S
triceps brachii: extension
anconeus: elbow extension (lateral epicondyle of humerus to olecranon proc of ulna)
supinator: supination (lateral epicondyle of humerus to post surf of radius)
name the 3 muscles that attach at the coracoid process
hint: P.M, S, C.B
pec minor, short end of scapula, coracoid brachialis
