Q. Do you have to think to move an involuntary muscle?
Involuntary muscles don’t need you to think about moving them. Some examples are: The muscles in your heart, which keep blood pumping round your body. The muscles in your digestive system which move food down to your stomach and keep moving it along your bowel until all the goodness that your body needs is taken out.
Q. What must skeletal muscles do 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.

Q. Where is the longest axon in the body located?
The longest axons in the human body are those of the sciatic nerve, which run from the base of the spinal cord to the big toe of each foot. The diameter of axons is also variable. Most individual axons are microscopic in diameter (typically about one micrometer (µm) across).
Q. Which axons are most sensitive to drugs?
Central axons preparing to myelinate are highly sensitive [corrected] to ischemic injury.
Q. How long is the longest neuron in the body and where is it located?
The longest neuron in the human body has a single threadlike projection (the axon), a few micrometers in diameter, that reaches from the base of the spine to the foot, a distance of up to one meter.” For axon length of over a meter see Cavanagh (1984, PMID 6144984 p.
Q. What animal has the largest nervous system?
The octopus has the most complicated brain of all the invertebrates. The octopus nervous system has about 500,000,000 neurons, with two-thirds of these neurons located in the arms of the octopus. Neurons in the octopus brain are arranged in lobes and tracts that are more specialized than simple ganglia.
Q. Which animal has no nervous system?
sponges
Q. What animal uses the most of their brain?
Dolphins
Q. What animal has the smoothest brain?
The amazing thing about a koala brain, besides the small size, is that it is relatively smooth! Smooth brains are called “lissencephalic” and it isn’t uncommon for a primitive animal like Koalas; koala-like animals date back 25-40 million years.
Q. Which animal has no brain and heart?
Jellyfish
Q. Do any animals have 2 Hearts?
Some animals like the octopus have more than one heart. An octopus has one main, systemic heart that pumps blood to the whole of its body. But it also has two additional hearts, responsible for pumping blood over each of its gills.
Q. What animal has 9 hearts?
octopuses
Q. Which animal milk is black?
Black Rhinoceros (Diceros bicornis) This dilute milk may have something to do with the animals’ slow reproductive cycle. Black rhinoceroses become capable of reproducing only once they reach four to five years old.
Q. Which animal milk is most expensive?
donkey milk
Q. What animal milk do humans drink?
Aside from cattle, many kinds of livestock provide milk used by humans for dairy products. These animals include water buffalo, goat, sheep, camel, donkey, horse, reindeer and yak.
Q. Which animal milk is best for human?
SHIRA SAYS: “Research suggests that camel’s milk is pretty much the closest you can come to a human mother’s milk, particularly in terms of immune-boosting proteins like lactoferrin and immunoglobulins. Camel’s milk also contains exclusively A2 casein, making it more digestible and better tolerated than cow’s milk.
