6. Posterior muscles of the forearm (Extensor compartment)

7. Muscle groups of the hand
1-Thenar (thumb) muscles
2-Hypothenar (little finger) muscles
They abduct, flex and appose the thumb and little fingers
Interossei muscles (four dorsal and three palmer) originating between the metacarpal bones
They abduct (Dab) and adduct (Pad) the fingers 
Lumbrical muscles arising from the deep flexor Tendons (they are special because they have no bony origin) to insert on the dorsal tendons of the fingers
They extend interphalangeal joints

8. Thenar and Hypothenar muscles

10. Muscles of the chest wall
Intercostal muscles
1- External intercostal muscle
2- Internal intercostal muscle
3- Innermost intercostal muscle
They Assist in
Respiration
Intercostal muscles

11. Muscles of abdominal wall
1-Rectus abdominis muscle
2-External abdominis oblique muscle
3-Internal abdominis oblique muscle
4-Transversus abdominis muscle
5- Diaphragm
Functions of abdominal muscles
1-Flex the trunk and increase the intra abdominal pressure
They aid defecation and micturition (urination)

12. Muscles of Abdomen

13. Muscles of the lower limb
Gluteal muscles
They make up the buttocks: they are 
1- gluteus maximus
2-  gluteus medius
3- gluteus minimus
The three muscles originate from the ilium and sacrum and insert on the femur.
The functions of the muscles include extension, abduction, external rotation and internal rotation of the hip joint

15. Lateral rotator group of the hip joint (deep posterior group)
This group consists of the 
1- Obturator Externus
2- Obturator Internus
3- piriformis  
4- Superior Gemellus
5- Inferior Gemellus  
6- Quadratus Femoris
These six originate at or below
the acetabulum of the ilium
and insert on or near the
greater trochanter of the femur.
They are lateral rotator of the hip

16. Hamstring group (posterior compartment of thigh)
Semimembranosus 
Semitendinosus 
Biceps femoris
They flex the knee joint

17. Adductor muscles of the hip .
The adductor brevis
Adductor longus
Adductor magnus 
Pectineus
Gracilis 
The adductors all originate
on the pubis and insert on
the medial, posterior
surface of the femur
They adduct the thigh

18. Muscles of anterior aspect of the thigh
Iliopsoas
Sartorius Flexors of the hip and knee joint
Quadriceps muscles
1- Rectus femoris muscle 
2- Vastus medialis
3- Vastus intermedius Extension of knee joint
4- Vastus lateralis
All four parts of the quadriceps muscle attach to the patella through the quadriceps tendon.

19. Quadriceps Muscles Thigh anterior view
The Vastus Intermedius muscle is
underneath Rectus femoris muscle
Quadriceps Muscles

20. Muscles of anterior aspect of the leg
Tibialis anterior
Extensor hallucis longus Dorsiflex
Extensor digitorum longus the foot
Peroneus tertius
Muscles of Lateral compartment of the leg
1-Peroneus (Fibularis)
Longus
2-Peroneus Brevis Flex and Evert the foot

21. Posterior compartment of the leg
1-Superficial posterior compartment
gastrocnemius
soleus
Plantaris
They form the
Achilles tendon
Which is inserted
Into the calcaneus
They planter flex the
foot

22. Deep posterior compartment of the leg
flexor hallucis longus
flexor digitorum longus They planter flex the foot and toes
tibialis posterior
popliteus
