### body part | appendage:

Limb
* All limbs are jointed, tubular and operate by way of muscles
  - have five digits
* Most limbs are part of endoskeletons
  - facilitate movement
* Most limbs have basic structures
  - bones
  - capacity
  - positions
* Most limbs have same basic structures
  - toes
  - support weight
  - use for locomotion
* Some limbs grow from buds.
* Some limbs have claws
  - feet
  - mechanisms
  - maintain contact
  - promote growth
* are adaptation for locomotion in shallow water
  - also extremely thin and long, out of proportion to the body
  - appendages
  - arcs
  - branchs
  - commonly contracted and necks are pulled back, in poses indicative of dessication
  - connected to the rest of the skeleton by collections of bones known as girdles
  - extremities
  - flippers adapted for swimming
  - free of any heat and swellings
  - legs and arms of a mammal, often with strong bones
* are part of bows
  - octants
* can break off due to the weight of fruit and larger trees require limb supports
  - grow at different rates, leaving teens uncoordinated, clumsy, and even weak
* contain resin ducts filled with aromatic triterpenes and ethereal oils.
* have a limited number of tissue types
  - arrangements
* includes corpi.
* injured by lightning, wind or disease die and eventually fall to the forest floor.
* stretch upward to the sun.
* tend to persist on the straight central trunks
  - persist, particularly on trees grown without severe competition
* twitch due to the lack of calcium which is required by the nervous system to operate properly.
* work and reach after the sun-down
  - as levers

+ Tiger Salamander, Description
  * The larvae are entirely aquatic, and are characterized by large gills on the outside and a big tail fin that begins just behind the head. Arms are grown within a short time of coming out of their egg. Some larvae, especially in pools that are here one season and gone the next and in the north, may metamorphose as soon as feasible. These are known as small morph adults. Other larvae, especially in ancestral pools and warmer climates, may not metamorphose until fully adult size. These large larvae are usually known as waterdogs, and are used many times in the fishing bait and pet trade. Some populations may not metamorphose at all, and become sexually mature while in their larval form.
