Topics	Upper limb			Lower limb
Size	Smaller and shorter			Larger and longer
Bones	Smaller and weaker			Larger and stronger
Movement	More movable			Less movable
Attachment with girdle	Less firmly attached			More firmly attached
Carrying angle	Present			Absent
Angle of inclination	Absent			Present
Position of flexor muscle	Anteriorly			Posteriorly
Position of extension muscle	Posteriorly			Anteriorly
Joints	Smaller and less stable			Larger and more stable
Muscles	Larger and attached to larger bony areas			Smaller and attached to small bony areas
Anti gravity muscle	Less develop			More develop
Pre-axial border	Faces laterally			Faces medially
Post axial border	The medial aspect of the upper arm.			the lateral aspect of the lower leg
Plexus	Supply by brachial plexus			Supply by lumbar and sacral plexus
Rotation of limb buds	90ᵒ lateral rotation so thumb directed laterally			90ᵒ medial rotation lateral rotation, so big toe directed medially
Time of development	4th week of development			4 week and 4 days
Time of appearance of bones in intrauterine period	Humerus  are seen at 8 weeks of development			Femora are seen at 9th weeks of development
Blood supply	Right and left subclavian artery			Right and left femoral artery mainly
Venous drainage	Less developed Two system: superficial and deep			More developed Three system : superficial, perforating and deep
Girdle	Pectoral girdle Made up of two bones clavicle and scapula No articulation with vertebral column Articulation with axial skeleton is very small through sternoclavicular joint			Pelvic girdle Made up of single bone the hip bone Articulation with vertebral column Articulation with axial skeleton is large through sacroiliac joint
Functions	Grasping and skilled movement			Weight bearing and locomotion
Segments	Arm	Forearm	Hand	Thigh	Leg	Foot
Bony framework	Single bone Humerus
Compartment	Two an	Two		Three	Three
Nerve supply	Anterior compartment is supply by musculocutaneous nerve Posterior compartment is supply by radial nerve	Posterior  compartment is mainly supply by median nerve and partly by ulnar nerve		Anterior compartment is supplied by femoral nerve, medial compartment is supplied by obturator nerve and posterior compartment is supplied by tibial nerve	posterior compartment is supplied by deep peroneal nerve,, lateral compartment is supplied by superficial peroneal nerve posterior compartment is supplied by tibial nerve
