Limb (anatomy)
A limb (from Old English ''lim'', meaning "body part") is a jointed, muscled appendage of a tetrapod vertebrate animal used for weight-bearing, terrestrial locomotion and physical interaction with other objects. The distalmost portion of a limb is known as its extremity. The limbs' bony endoskeleton, known as the appendicular skeleton, is homologous among all tetrapods, who use their limbs for walking, running and jumping, swimming, climbing, grasping, touching and striking. All tetrapods have four limbs that are organized into two bilaterally symmetrical pairs, with one pair at each end of the torso, which phylogenetically correspond to the four paired fins ( pectoral and pelvic fins) of their fish ( sarcopterygian) ancestors. The cranial pair (i.e. closer to the head) of limbs are known as the forelimbs or ''front legs'', and the caudal pair (i.e. closer to the tail or coccyx) are the hindlimbs or ''back legs''. In animals with a more erect bipedal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand
A hand is a prehensile, multi-fingered appendage located at the end of the forearm or forelimb of primates such as humans, chimpanzees, monkeys, and lemurs. A few other vertebrates such as the Koala#Characteristics, koala (which has two thumb#Opposition and apposition, opposable thumbs on each "hand" and fingerprints extremely similar to human fingerprints) are often described as having "hands" instead of paws on their front limbs. The raccoon is usually described as having "hands" though opposable thumbs are lacking. Some evolutionary anatomists use the term ''hand'' to refer to the appendage of digits on the forelimb more generally—for example, in the context of whether the three Digit (anatomy), digits of the bird hand involved the same Homology (biology), homologous loss of two digits as in the dinosaur hand. The human hand usually has five digits: Finger numbering#Four-finger system, four fingers plus one thumb; however, these are often referred to collectively as Finger ...

Foot
The foot (: feet) is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is an organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails. Etymology The word "foot", in the sense of meaning the "terminal part of the leg of a vertebrate animal" comes from Old English ''fot'', from Proto-Germanic *''fot'' (source also of Old Frisian ''fot'', Old Saxon ''fot'', Old Norse ''fotr'', Danish ''fod'', Swedish ''fot'', Dutch ''voet'', Old High German ''fuoz'', German ''Fuß'', Gothic ''fotus'', all meaning "foot"), from PIE root *''ped-'' "foot". The plural form ''feet'' is an instance of i-mutation. Structure The human foot is a strong and complex mechanical structure containing 26 bones, 33 joints (20 of which are actively articulated), and more than a hundred muscles, tendons, and ligaments.Podiatry Chan ...

Appendage
An appendage (or outgrowth) is an external body part or natural prolongation that protrudes from an organism's body such as an arm or a leg. Protrusions from single-celled bacteria and archaea are known as cell-surface appendages or surface appendages. In many kinds of eukaryotic cells, the protrusions are known as membrane protrusions or cell appendages (examples include microvilli and cilia). Types in animals In arthropods, an appendage refers to any of the homologous body parts that may extend from a body segment, including antennae, mouthparts (including mandibles, maxillae and maxillipeds), gills, locomotor legs ( pereiopods for walking, and pleopods for swimming), sexual organs ( gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. An appendage which is modified to assist in feeding is known as a maxilliped or gnathopod. In annelids lateral protrusions from the body are called parapodia. In echinoderms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extremities (play)
''Extremities'' is an off-Broadway play by William Mastrosimone and directed by Robert Allan Ackerman. It opened at the Westside Theatre in New York on December 22, 1982 and ran for 325 performances. Plot A young woman, Marjorie, is attacked in her home by a would-be rapist, Raul, and manages to turn the tables on him, tying him up in her fireplace. Her roommates come home to discover the attacker bound with cords, belts and other household items. Terry and Patricia, the roommates, express different points of view about rape in society. Terry, a rape victim herself as a teenager, believes that Raul will not be convicted because a rape did not actually occur and there is no proof. Patricia believes in the judicial system and insists on calling the police. The three friends also turn on each other at various points in the play, due to Raul's knowledge of each through stalking them. For instance, close to the play's opening, Raul reveals to Terry that Marjorie had been having a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extremities (film)
''Extremities'' is a 1986 American drama film directed by Robert M. Young and written by William Mastrosimone, based on his 1982 off-Broadway play of the same name. The film stars Farrah Fawcett, Alfre Woodard, Diana Scarwid, and James Russo. Both Fawcett and Russo had appeared in the stage play (Fawcett taking over a role originated by Susan Sarandon), and Fawcett received a Golden Globe nomination for Best Actress for her performance in the film. Plot While getting into her car one night, Marjorie is attacked at knifepoint by a masked assailant who forces her to drive to a remote location, where he tries to sexually assault her. She manages to flee but leaves her purse behind. While at the police station, she is told that without a positive identification of her attacker, there is little they can do to help— and if he is found, it will be her word against his, and he will likely not face any criminal charges. In the following days, Marjorie lives in continued fear. Mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
