bio 108 CP #2 muscles that share similar landmarks

Anterior Superior Iliac Spine (ASIS) of the hip bone

Sartorius (originates from the ASIS)

Tensor Fasciae Latae (originates near the ASIS on the iliac crest)

Ischial Tuberosity of the pelvis

Hamstring group::

(biceps femoris,

semitendinosus,

semimembranosus)

adductor magnus (posterior part) all share origin points here.

Greater Trochanter of the femur

Piriformis,

obturator internus,

superior/inferior gemelli,

GLUTEUS MEDIUS

GLUTEUS MINIMUS

attach around or on this prominent bony knob

Coracoid Process of the scapula

Biceps brachii (short head),

coracobrachialis,

pectoralis minor

all attach to this small hook-like projection on the shoulder blade

Medial Epicondyle of the humerus (the "funny bone" side)

A common flexor tendon anchors multiple superficial forearm muscles here, including the

pronator teres,

flexor carpi radialis,

palmaris longus,

flexor carpi ulnaris

Greater Tubercle of the Humerus

Three of the four rotator cuff muscles

(supraspinatus,

infraspinatus,

teres minor)

insert onto separate facets on this prominence

Lateral Epicondyle of the Humerus

The common extensor tendon attaches here, serving as the shared origin for superficial forearm extensors like the

extensor carpi radialis brevis,

extensor digitorum, and

extensor carpi ulnaris

tibia, medial condyle

Three muscles from three different thigh compartments converge to insert onto this shared area on the shinbone:

sartorius,

gracilis,

semitendinosus

Tibial Tuberosity

All four muscles of the quadriceps group

rectus femoris,

vastus lateralis,

vastus medialis,

vastus intermedius

insert here together via the patellar ligament.

Linea Aspera of the Femu

This long ridge on the back of the thigh bone acts as a shared attachment for

adductors (longus, brevis, magnus), vastus medialis, vastus lateralis, and

short head of the biceps femoris.

Calcaneal Tuberosity (Heel Bone)

gastrocnemius,

soleus

plantaris

share this insertion site by merging into the calcaneal (Achilles) tendon.

Mastoid Process of the Skull

This bony bump behind the ear is a shared insertion for

sternocleidomastoid,

splenius capitis, and

longissimus capitis

Iliac Crest

This large curved ridge at the top of the pelvis provides attachment points for major core and hip muscles, including the

external oblique,

internal oblique,

transversus abdominis

, quadratus lumborum,

latissimus dorsi, and

gluteus medius

Medial Border of the Scapula

levator scapulae,

rhomboid minor,

rhomboid major, and

serratus anterior

all attach along this inner edge of the shoulder blade

anterior surface of distal humerus

brachialis

Spine of the Scapula

This ridge serves as an insertion point for the

trapezius on its superior lip and

an origin for the

posterior deltoid on its inferior lip.

lesser turbecle of humerus

subscapularis
