In human anatomy, the upper limb (also upper extremity) refers to what in common English is known as the arm, that is, the region of the shoulder to the fingertips. Human anatomy, which with physiology and biochemistry is a complementary basic medical science is primarily the scientific study of the morphology of the adult Human body A limb (from the Old English lim) is a jointed or Prehensile (as Octopus tentacles or new world Monkey tails Appendage of the It includes the entire limb, and thus, is not synonymous with the term upper arm.
General structures
The upper limb includes the following structures:
- Shoulder
- Arm (proper) - in anatomy, the region between the shoulder and the elbow
- Elbow
- Forearm
- Wrist
- Hand
Note that anatomists use the term arm to denote only the region between the shoulder and the elbow. In Human anatomy, the shoulder joint comprises the part of the body where the Humerus attaches to the Scapula. In Anatomy, an arm is one of the Upper limbs of an animal The term arm can also be used for analogous structures such as one of the paired upper limbs The elbow is the region surrounding the elbow-joint&mdashthe ginglymus or Hinge joint in the middle of the Arm. The forearm is the structure on the Upper limb, between the elbow and the Wrist. In Human anatomy, the wrist is the flexible and narrower connection between the Forearm and the palm. The hands ( med / lat: manus pl manūs are the two intricate prehensile multi- Fingered body parts normally located at the end of each arm of a This is in contrast to the proper English definition. Anatomists also use the term leg to refer to the region between the knee and the ankle. This, however, is the proper and traditional usage of the word, even though popular modern usage tends to include the thigh and foot in the definition.
Bones
The following bones are considered to be part of the upper limb:
- Clavicle - the only bone that directly articulates with the trunk
- Scapula
- Humerus
- Radius
- Ulna
- Carpal bones
- Metacarpals
- Phalanges
