'''Extremities''' are the outermost parts of the body, including the [[hands]], [[feet]], [[arms]], and [[legs]]. They play a crucial role in mobility and manipulation, allowing humans to interact with their environment.

== Anatomy of Extremities ==

The human body has four extremities: two upper and two lower. The upper extremities consist of the [[shoulder]], [[arm]], [[forearm]], [[wrist]], and [[hand]]. The lower extremities include the [[hip]], [[thigh]], [[leg]], [[ankle]], and [[foot]].

=== Upper Extremities ===

The upper extremities start from the shoulder and end at the hand. The [[shoulder joint]] is the most mobile joint in the body, allowing the arm to move in multiple directions. The arm consists of the [[humerus]], the largest bone in the upper body. The forearm contains two bones, the [[radius]] and [[ulna]], and leads to the wrist. The hand consists of 27 bones, including the [[carpals]], [[metacarpals]], and [[phalanges]].

=== Lower Extremities ===

The lower extremities begin at the hip and end at the foot. The hip is a ball-and-socket joint that connects the [[pelvis]] to the [[femur]], the longest bone in the body. The leg contains two bones, the [[tibia]] and [[fibula]], and leads to the ankle. The foot consists of 26 bones, including the [[tarsals]], [[metatarsals]], and [[phalanges]].

== Functions of Extremities ==

Extremities are essential for various functions, including mobility, balance, and manipulation. They allow humans to walk, run, jump, lift, carry, and perform fine motor tasks. They also play a role in body language and non-verbal communication.

== Health and Extremities ==

Various health conditions can affect the extremities, including [[arthritis]], [[fractures]], [[sprains]], and [[neuropathy]]. These conditions can cause pain, swelling, stiffness, numbness, and reduced mobility. Treatment options include medication, physical therapy, surgery, and lifestyle changes.
