How are the scales arranged on the trunk and tail of the perch?
they are arranged by the fins
In what order would methods of absorption be arranged from fastest to slowest?
The order in which the methods of absorption are arranged from the fastest to the slowest are Injection, Oral, and Topical.
Does a worm have a exoskeleton?
A hydrostatic skeleton or hydroskeleton is a structure found in many cold-blooded organisms and soft-bodied animals consisting of a fluid-filled cavity, the coelom, surrounded by muscles. Some examples are soft bodied animals such as sea anemones and earthworms. Hydrostatic skeletons have a role in the locomotion of echinoderms (starfish, sea urchins), cnidarians (jellyfish), annelids (earthworms), nematodes, and other invertebrates. They have some similarities to muscular hydrostats.
What is the fiber direction of a cats internal oblique muscles?
The cat's muscle fibers run perpendicular to its internal oblique muscles. The fibers of the external oblique muscles run opposite of the muscles.
Are the muscles of a chickens wing antagonistic?
The muscles of a chickens wing are antagonistic. Antagonistic muscles are the ones that oppose a specific type of movement.
How does a sea anemone stand straight?
They are supported by their hydroskeleton.
Most cnidaria possess a skeletal system known as a?
Hydroskeleton
What does an earthworm receives support and shape from its fluid-filled cavity?
hydroskeleton
What kind of muscles are elongated arranged in sheets and contain multiple nuclei?
Muscle cells
What type of of muscles that has a single nucleus spindle shaped and arranged in parallel pattern?
Skeletal muscle
Are there muscles in your palm?
Yes, and there are muscles throughout your entire body. If there were no muscles in your palm, you wouldn't be able to crush anything in it, and the middle of your hand, theoretically, would be squishy and useless.
How are the muscle cells arranged with respect to one another?
Muscle fibers are grouped into fascicles, these fascicles form a muscle. The fascicles are arranged in 3 basic patterns. Parallel fascicles are arranged length wise in a parallel form. Circular fascicles are arranged in rings in a concentric pattern. Pennate fascicles are arranged in a feather pattern, with muscles arranged like a feather attached to a tendon along its length.
What are the forces in muscles?
When muscles are stimulated, they contract, causing the muscle to become shorter. The force applied is therefore a tension. Most muscles are arranged in pairs so that each can apply tension to move a joint in either direction. Obvious examples of the pairing of muscles can be seen at the elbow and knee.
How are muscle fibers arranged to form a muscle?
Muscle fibers can be arranged into two basic structural patterns, fusiform and pinnate. Most human muscles are fusiform, with the fibers largely arranged parallel along the muscle's longitudinal axis. In many of the larger muscles the fibers are inserted obliquely into the tendon, and this arrangement resembles a feather. The fibers in a pinnate (feather) muscle are shorter than those of a fusiform muscle. The arrangement of pinnate muscle fibers can be single or double, as in muscles of the forearm, or multipinnate, as in the gluteus maximus or deltoid.
Longitudinally and circularly arranged layers in muscle?
Smooth muscle tissue has longitudinally and circularly arranged layers.
Do cardiac muscles work in pairs?
No, cardiac muscles do not work in pairs. They are arranged in a network within the heart and work together in a coordinated manner to contract and pump blood throughout the body. The contraction of cardiac muscles is regulated by electrical signals from the heart's pacemaker cells.
Why skeleton muscles or voluntary muscles are arranged in antagonistic pairs?
Voluntary Muscles can contract or pull but, they cannot push. When they are finished pulling and are relaxed, their antagonists on the other side of the couple must pull the joint back.
