What are some good facts about the muscular system? Please hurry

Answers

Answer 1
Interesting Muscles Facts:Muscles make up about 40% of total body weight.The smallest muscles, like the smallest bones, are found in the middle ear, some of these are the tensor tympani (connected to the ear drum) and the Stapedius.Muscles cannot push, they can only pull. The reason the arm can push is muscles in the back of the arm pulling on the elbow!The strongest muscles in the body? Pound for pound, it's the muscles that you chew with - called the masseters!Humans are born with all of the muscle fibers they will ever have. They don't grow new fibers, they just grow thicker.If all of the muscles in the body could all pull in one direction, it would create a force of 25 tons!Smiling takes 17 muscles in the face, while frowning takes 43!The heart is made up of muscle, called cardiac muscle. This muscle works all by itself with no thought. The heart beats anywhere from 60 to 100 times a minute, every minute, of every day in a human life!The skeletal muscles, which are the ones that can be controlled by conscious thought, work with the skeleton, or the bones, to move the body. They attach to the skeleton with tendons, which are cords of tough tissue.Some of the biggest muscles are in the back, near the spine. They are responsible for keeping the body upright and gives the body the power it needs to lift and push things.Skeletal muscles are also sometimes called striated muscle - this name comes from the light and dark parts of the muscle fibers making them look striped (striated means striped).Smooth muscles, which can't be voluntarily controlled, usually occur in sheets or layers, one layer of muscle behind another. These are at work all over your body.In the digestive system, the smooth muscles tighten up and relax, moving food through the body.Smooth muscles are also found in the bladder. When they are relaxed, the opening in the bladder is closed, which allows urine to stay in the bladder. When someone goes to the bathroom, they contract, which pushes urine out of the bladder.Smooth muscles in a woman's uterus, which is where a baby develops and grows, push the baby out when it's time to be born.Smooth muscles are even found in the eyes, where they help keep the eyes focused, and help control the amount of light that enters the eye.

Imagine that you have decided to try out a new kind of food that your friend has made for you. You pick it up and take a bite, and it tastes awful. You are wondering if you should tell your friend what you really think. Give an example of how each of these parts of the brain would be involved in your experience:
hindbrain
forebrain
midbrain

(This is not a multiple choice question)

Answers

Final answer:

The hindbrain might trigger a reflex to swallow or gag upon tasting the unpleasant food. The midbrain registers the bad taste and aroma while the forebrain decides, based on higher thought processes, whether or not to tell your friend.

Explanation:

In this scenario, all three parts of your brain - the hindbrain, midbrain, and forebrain - would be involved in processing this unpleasant food experience.

The hindbrain is responsible for more primal functions, such as swallowing and gagging. When you take a bite of the food and dislike it, your hindbrain might trigger a gag reflex or the need to swallow quickly to get the taste out of your mouth.

The midbrain plays a role in sensory perception, such as taste and smell. It might register the unpleasant taste and aroma of the food.

The forebrain is responsible for higher thought processes. After the taste and aroma of the food are registered, your forebrain would be engaged in deciding whether or not to tell your friend about your dislike of the food based on factors such as not wanting to hurt their feelings.

What type of exercises should a 55-year-old woman do to help fight against osteoporosis? A. aerobic exercises B. conditioning exercises C. stretching exercises D. weight-bearing exercises

Answers

To combat osteoporosis, a 55-year-old woman should prioritize weight-bearing exercises such as weight training, dancing, and stair climbing, which are known to improve bone mineral density and overall bone health, option D is correct.

To help fight against osteoporosis, a 55-year-old woman should focus on weight-bearing exercises. These exercises are essential for maintaining and increasing bone mineral density (BMD), which helps prevent the development of osteoporosis. Engaging regularly in weight-bearing exercises like strength training with weights, dancing, stair climbing, running, and hiking can stimulate the bones in a way that promotes bone health. These activities not only reduce the risk of osteoporosis but also help maintain muscle mass and improve cardiovascular health.

While aerobic exercises and stretching exercises contribute to overall fitness, they do not have the same direct impact on bone density as weight-bearing activities do. It's recommended to participate in such exercises for at least 30 minutes a day on most days of the week. Additionally, for those who are able to do so, resistance exercises can also be beneficial by putting stress on the bones, which encourages bone growth.

Propose reasons why an antibiotic may not be as effective at inhibiting
e. coli as it is against
b. cereus.

Answers

Final answer:

An antibiotic may be less effective against E. coli than B. cereus due to differences in their cell wall structures, E. coli's developed antibiotic resistance, and patient non-compliance with treatment regimens.

Explanation:

An antibiotic may not be as effective at inhibiting E. coli as it is against B. cereus for several reasons. One possible reason is the difference in cell wall structure between Gram-negative bacteria like E. coli and Gram-positive bacteria like B. cereus. Gram-negative bacteria have an outer membrane that can block the entry of certain antibiotics, making them inherently more resistant to those drugs.

Furthermore, E. coli has developed antibiotic resistance through both the acquisition of resistance genes via horizontal gene transfer and the selection for resistant strains due to excessive use of antibiotics. For example, the MCR-1 gene, which confers resistance to colistin—a last-resort antibiotic—is often found on plasmids that can be transferred between bacteria. In contrast, B. cereus is less notorious for carrying such resistant plasmids. Lastly, patient compliance with prescribed antibiotic regimens can impact effectiveness as patients who do not complete the full course of antibiotics increase the potential for bacteria to develop and spread resistance.
