Smooth muscle is responsible for the contraction that moves limbs.
No, the trapezius is not an abductor. It is a large muscle that extends from the back of the neck down to the mid-back and across the shoulders. Its primary functions include stabilizing, raising, and retracting the scapula, as well as extending the neck. Abduction typically refers to the movement of limbs away from the body's midline, which is not a primary role of the trapezius.
Recumbent limbs on a tree refer to branches that grow horizontally or at a low angle, often lying close to the ground rather than extending upward. These limbs can develop due to various factors, including the tree's species, environmental conditions, or genetic traits. Recumbent limbs may impact the tree's overall shape and health, and can sometimes provide habitat for wildlife or promote the growth of certain understory plants.
A property owner is responsible for trimming or removal of trees that are a 'known" hazard to the life, health or property of others.

The body axis of a four-legged animal is typically horizontal, with the spine running parallel to the ground and limbs extending out to the sides. In contrast, the body axis of a human is vertical, with the spine running perpendicular to the ground and limbs extending downward. This difference in body axis affects posture, movement, and overall body structure between the two types of animals.
The cervical enlargement contains nerves that supply the upper limbs, shoulders, and neck muscles. It is responsible for coordinating motor function in this area of the body.
Urodeles, commonly known as salamanders, typically have two pairs of limbs, totaling four limbs. These limbs are adapted for various forms of locomotion, including walking and swimming. Some species may exhibit variations in limb morphology, but the standard limb count remains consistent across the group.
The muscular system is responsible for moving the limbs. Muscles work in coordination with the skeletal system to produce movement. Nerves from the nervous system send signals to the muscles to contract and allow for precise control of limb movement.
The gangly teenager awkwardly shuffled across the room, his limbs appearing disproportionately long and ungainly.
The flexors are in the muscular system and their function is to bend limbs.
8 major limbs
The tetrapod is an example of an early amphibian. It was very similar to a fish but had limbs which it used to move across the bottom of marches.
