How do animal muscles move ? The muscle cells move by contraction and relaxation by utilizing the energy in the form of ATP. ... During relaxation the muscle fibres come to their original position. This movement of muscles cells or the muscle fibres results in the movement of the body parts.

The chest muscles are responsible for moving the arms across the body and up and down, as well as other movements like flexion, adduction, and rotation. Most chest exercises will involve pushing the arms away from the body or the body away from the arms.

Birds obtain thrust by using their strong muscles and flapping their wings. Some birds may use gravity (for example, jumping from a tree) to give them forward thrust for flight. Others may use a running take-off from the ground.

Some cells must be able to move (like sperm cells), while other cells need to contract (like muscle cells). Three of the many specialized cell types in animals include red blood cells, muscle cells, and skin cells.

A bird has wings which helps it to fly. Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily.

Skeletal Muscles and Bones Many skeletal muscles are attached to the ends of bones that meet at a joint. The muscles span the joint and connect the bones. When the muscles contract, they pull on the bones, causing them to move.

Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can't push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint.

Although the striated muscles (muscles for movement) connect with muscle fibers and tissues in both species, the number and types of bones effect specialized movement. For example, humans have 24 vertebrae that allow for back arching movements, while frogs have only nine.

Differences between plants and animals: Locomotion: Plants generally are rooted in one place and do not move on their own (locomotion), whereas most animals have the ability to move fairly freely. Photosynthesis: Plants contain chlorophyll and can make their own food, this is called Photosynthesis.

Living things can move bodily or show movement of parts of organs of their body in response to external stimuli. Non-living things never move on their own effort. Living organisms respond to external stimuli. Non-living things have no power to respond to external stimuli.

Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily. ... This shape helps the bird to fly.

Skeletal muscles move the body. Skeletal muscle contractions pull on tendons, which are attached to bones. If contraction of the muscle causes the muscle to shorten, the bone and, thus, the body part will move. ... Contraction and, thus, shortening, of the biceps brachii pulls on the tendons attached to the bones.

Skeletal muscles are attached to bones and allow voluntary movement of the body. Smooth muscles, which generate involuntary movement, form part of the walls of the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, and blood vessels, among other portions of the body.

Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily. ... To stop, the bird spreads out its wings and stretches its feet.

Skeletal muscle is made up of voluntary muscles, usually attached to the skeleton. Skeletal muscles move the body. They can also contract involuntarily by reflexes. For example, you can choose to move your arm, but your arm would move automatically if you were to burn your finger on a stove top.

Skeletal muscles produce movements by pulling on tendons, which in turn pull on bones. Usually, a muscle is attached to two bones via a tendon on each end of the muscle. When the muscle contracts, it moves one bone toward the other. ... In addition, most skeletal muscles are arranged in opposing pairs at joints.

Striated muscles are highly organized tissues (Fig. 1) that convert chemical energy to physical work. The primary function of striated muscles is to generate force and contract in order to support respiration, locomotion, and posture (skeletal muscle) and to pump blood throughout the body (cardiac muscle).
