Name 21 vestigial organs in humans?
The appendix, tonsils, wisdom teeth, tailbone (coccyx), plica semilunaris, and arrector pili muscles are commonly cited as vestigial organs in humans. These organs are remnants of structures that were functional in our evolutionary ancestors but have reduced or lost their original function in modern humans.
Do animal muscles have the same muscles as the human body?
Animals have similar muscles to those in the human body, but there can be variations in the size and arrangement of muscles based on the species. All animals have muscle tissue composed of muscle fibers that contract to generate movement. While the specific muscles may vary in name and function between humans and animals, the overall structure and purpose of muscles are comparable.
How does the semimembranosus compare with its human homologue?
The semimembranosus muscle in animals is a homologous structure to the hamstring muscles in humans. It functions to flex the knee joint and extend the hip joint in animals, similar to its function in humans. However, there are differences in size and morphology between the animal semimembranosus and the human hamstring muscles.
Animals with Endoskeleton?
Animals with endoskeletons include humans, fish, birds, and mammals. Endoskeletons provide internal support and protection for the body's soft tissues, muscles, and organs.
Do the trapezius muscle appear to have the same functions in cats as in humans?
The one deltoid muscle in humans is 3 muscles in cats: the clavobrachialis, acromiodeltoid, and spinodeltoid muscles. Also, the deltoid muscle in a cat does not connect directly to its skeletal frame, whereas in a human it does.
What are arrector glands?
Arrector glands, more commonly referred to as arrector pili muscles, are small muscles located at the base of hair follicles in mammals. When these muscles contract, they cause the hair to stand upright, a phenomenon known as piloerection, which can occur in response to cold temperatures or emotional stimuli. This response is often associated with "goosebumps." While these muscles play a role in thermoregulation and social signaling, they do not have significant functionality in humans compared to other animals.
Is arrector pili muscles associated with hair follicles?
Yes, arrector pili muscles are associated with hair follicles. Arrector pili muscles are in the skin, connected to the hair follicles. Their job is to help maintain body homeostasis. When we are cold, the arrector pili muscles shorten, causing our hairs to stand up so that they block the cold and help keep heat from escaping. Although this is not very effective in humans because evolution has made us less hairy, this is great method for hairy animals to stay warm. Now you know why we get "goosebumps" when we are cold! :)
What is the most important role of the arrector pili muscles in humans?
It causes the hair follicle to stand erect
How do animals and humans move?
muscles

What function do goosebumps play in your integument?
Goosebumps are caused by the contraction of tiny muscles called arrector pili muscles attached to hair follicles. In animals, this response can help trap air to provide insulation or make the animal appear larger to predators. In humans, goosebumps are a vestigial response that has lost its original function but can be triggered by emotions or cold temperatures.
How many muscles does a human eye have?
animals have 4 big muscles, but humans have 6 muscles. Humans have 6 muscles to roll our eyes .

Are ear muscles vestigial in humans and what is their function?
Yes, ear muscles in humans are considered vestigial, meaning they have lost their original function over time. These muscles are remnants of our evolutionary past when our ancestors could move their ears to better detect sounds or communicate nonverbally. Today, these muscles no longer serve a significant purpose in humans.
Why are ear muscles considered vestigial in humans?
Ear muscles are considered vestigial in humans because they are remnants of muscles that were once used to move the ears in order to better detect sounds, a function that is no longer necessary for survival in modern humans.
What is a voluntary muscle is in an animal and what does it do.?
The muscles which are under the control of the brain are called voluntary muscles. Eg: the muscles in your hand, thigh etc., Humans are also animals.
