Q. When muscles attach to bones the end that moves when the muscle contracts is called the origin?
A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin. If the place is on the bone that moves during the action, the attachment is called an insertion.
Q. Which attachment of a muscle usually moves?
The origin is where the muscle joins the stationary bone. The insertion is where it joins the moving bone. When a muscle contracts, the insertion moves towards the origin. Tendons are the cords and straps that connect muscles to bones.

Q. What is an attachment to a moveable bone?
• Attachment to the more stationary bone by tendon closest to the body or muscle head or proximal is the. origin and attachment to the more moveable bone by tendon at the distal end is the insertion.
Q. What is an advantage of having hollow bones?
Hollow bones are also called pneumatized bones, meaning they’re filled with space for air. It is thought that this structure helps with oxygen intake during flight. Air sacs are attached to the hollow areas in a bird’s bones. Essentially, their lungs extend throughout their bones.
Q. What advantage do we gain from the fact that our bones are hollow?
Like all birds, whooping cranes have hollow bones that make their bodies lighter. With hollow bones a bird can fly very long distances without getting worn out from carrying its own weight. Hollow bones look like other bones, with the usual hard exterior you’d expect a bone to have.
Q. Are any human bones hollow?
If you looked at a cross section of your arm, you would be able to see that the bone is actually a hollow structure; in the middle is a cylinder. So, bones are actually hollow tubes, a bit like bamboo which is a type of plant.
Q. What is the strong connective tissue that holds the bones together in movable joints?
Ligaments
Q. Are hollow bones more fragile?
Bird skeletons don’t weigh any less than mammal skeletons of the same size. After all, thin, hollow bones are more fragile, so they’d need to be made of much denser material to keep from breaking all the time. That density also helps with flying, according to research out of the University of Massachusetts Amherst.
Q. Are owl bones hollow?
In owls, the skeleton makes up about 7-9% of its total body weight. Many of the bones which would be separated in mammals are fused together in birds, making them strong to support their weight on the ground. In addition, some of the larger bones are hollow, with bony internal bracing. This helps reduce overall weight.
Q. Which animal has the lightest bones?
Nevertheless, many people are surprised to learn that bird skeletons do not actually weigh any less than the skeletons of similarly sized mammals. In other words, the skeleton of a two-ounce songbird weighs just as much as the skeleton of a two-ounce rodent.
Q. Which flightless bird have heavy solid bones?
Ostriches
Q. Which bird can fly backwards?
Hummingbirds
Q. Is peacock can fly?
Peacocks can (sort of) fly – they tend to run and take several small leaps before a big final hop. They can’t stay airborne for very long, but their huge wingspan allows them to flutter quite far.
Q. Which is the fastest bird?
The Peregrine Falcon
Q. Who is faster peregrine falcon or Cheetah?
Fastest organism The fastest land animal is the cheetah, which has a recorded speed of between 109.4 km/h (68.0 mph) and 120.7 km/h (75.0 mph). The peregrine falcon is the fastest bird, and the fastest member of the animal kingdom, with a diving speed of 389 km/h (242 mph).
Q. What is the fastest flying insect?
Dragonflies
Q. Which is faster a bee or a fly?
They do neither. Their wings beat over a short arc of about 90 degrees, but ridiculously fast, at around 230 beats per second. Fruit flies, in comparison, are 80 times smaller than honeybees, but flap their wings only 200 times a second.
Q. What is the fastest human?
Usain Bolt
Q. What is the biggest bug ever?
Giant wētā
Q. Do WETA bites hurt?
Wētā can bite with powerful mandibles. Tree wētā bites are painful but not particularly common. Tree wētā lift their hind legs in a defence displays to look large and spiky, but they tend to retreat if given the chance.
Q. Which country has the most bugs?
The island country of Japan, however, is home to numerous forms of dangerous and even deadly forms of insect life. Considering Japan’s relatively small size along with the multitude of native insect pests, this country can be considered one of the most insect pest-populated countries in the world.
Q. What is the largest fly in the world?
Gauromydas heros
