No. The muscular opening is the anal sphincter, or simply, 'anus'. The part of the intestine that leads up to the anus is called the rectum. The rectum is more or less just a storage place until the intestine is ready to empty itself through the anus to the outside world.
Which muscle is the prime mover for arm abduction?
The latissimus dorsi is the muscle responsible for moving the arm posterior or backwards.
What is best treatment for sore muscles?
This might not be THE BEST, but it definitely works. follow all these instructions properly and you will make your sore muscles go away completely or at least suppress.
- Stretch all of your muscles, it is prefered that you stretch your muscles right after your work out to avoid sore muscles. But if you didn't, you can still do it now.
- Soak muscles in cold water, for at least 10 minutes.
- then soak muscles in warm water for at least 10 min.
- The soak muscles in cold water again for at least 5 min.
- Eat plenty of protein. Protein is the building blocks of muscles. (at least a 100 g).
- Take plenty of rest probably sleep.
Make sure you eat a lot of protein. if you don't, every thing else you do will be just a waste of time.
NOTE: If your muscles are sore, don't worry! muscle soreness is a good thing. Your muscles are sore because they are trying to build up. they don't want to be used while they are building up, so that's why they give you a sore feeling.
WARNING: Do NOT drink soda or energy drink (Monster, 5 hr energy, etc), if you have sore muscles. those things will make you hyper and you will lose the sense of soreness for short time. your muscles are still trying to build up but you will be using them because you are hyper. This will rip your muscle and will cause permanent damage.
How many muscles do adults have?
It depends on which muscle you consider a distinct versus a complex muscle. Over 650 in any case.
Adults have about 600-650 mussels in their bodies.
What are the different levels of organization of a muscle down to mayo filaments?
Muscle, fasicle, muscle fiber, myofibril, myofilament
What nervous system controls the skeletal muscle contractions?
The central nervous system supplies the body and muscle contraction. Striated muscle (skeletal muscle) contract voluntary with exception of the heart which is striated involuntary smooth muscle.

Muscles that work as opposite pairs to move bones are called?
Agonist & Antagonists
Agonist is the muscle responsible for the primary movement ( muscle that contracts)
Antagonist is the opposite muscle that must relax to allow the agonist to move a joint.
How can you take care of your muscular system?
to take care of your muscles you have to work out everyday and work on one muscle group at a time. don't let your body get to used to a work out. make sure you eat healty and don't drink alot of sugary or high in carb stuff. do weight training. ASK JOHN MORRISON! he knows what he's doing!
What does oxygen do in the muscles?
aorta....!!!!:D :) ;) :( <3 (^^^) try it facebook emoticons...!!!!!
When you want to move a muscle, your brain sends a message out to the muscle you want to move, and the muscle sends a message back to your brain that your moving it and where.
Guillain-Barre' Syndrome
About how many muscles are there in the human body?
There are approximately 650 skeletal muscles in the human body but an exact number is difficult to define. The difficulty lies in the fact that different sources group the muscles differently and some muscles are not always present.
Where are your tricep muscles located in your body?
The triceps are the large muscles on the back of upper arms.
What is the medical term meaning benign tumor of glandular tissue?
An adnoma is a benign tumor of a gland.
What are three characteristics of muscle you can observe under microscope?
Isometric,Isotonic and Twitch-these are the three characeteristics of muscle contraction.
The human skeleton is an endoskeleton (internal skeleton) made of bone and cartilage.
Major Functions
- Support for the soft tissues and largely responsible for the shape of the human body.
- Movement: the strong rigid bones function as levers moved by the contraction of muscles.
- The brain is protected by the skull.
- The heart and lungs are protected by the rib cage.
- The spinal cord is protected by the backbone
- Protection: the tough bones protect delicate vital organs
Structure
The skeleton is divided into:
1. Axial Skeleton: skull, backbone, ribs and sternum.
2. Appendicular Skeleton: pectoral girdle, pelvic girdle and limbs.
2. Spine or Backbone: Also known as the vertebral column. It is composed of 33 small bones in a line - cervical (7), thoracic (12), lumbar (5), sacrum (5), coccyx (4).
The vertebrae of the sacrum and coccyx are fused together. The vertebrae of the other regions can move slightly giving flexibility to the backbone. There are cartilage discs between these that act as shock absorbers. They help to protect the vertebrae. The vertebrae are held in position by ligaments. Muscles attached to their surfaces also support the vertebrae. Spinal nerves emerge in pairs from the spinal cord between the vertebrae.
Muscles
There are 3 types of muscle: skeletal, smooth, and cardiac.
Skeletal Muscle
Skeletal muscle, as its name implies, is the muscle attached to the skeleton. It is also called striated muscle. The contraction of skeletal muscle is under voluntary control. These muscles are mainly responsible for movement of the body. Other purposes are posture maintenance, support of the joints, and heat production. While its contraction is fast and strong, skeletal muscle tires easily.
Smooth Muscle
Smooth muscle is found in the walls of all the hollow organs of the body (except the heart). Its contraction reduces the size of these structures. Thus it regulates the flow of blood in the arteries, moves your breakfast along through your gastrointestinal tract, expels urine from your urinary bladder, sends babies out into the world from the uterus, and regulates the flow of air through the lungs. The contraction of smooth muscle is not under voluntary control. It is called involuntary muscle. It contracts slowly and is slow to tire.
Cardiac MuscleYour heart is made of cardiac muscle. This type of muscle only exists in your heart. Unlike other types of muscle, cardiac muscle never gets tired. It works automatically and constantly without ever pausing to rest. Cardiac muscle contracts to squeeze blood out of your heart, and relaxes to fill your heart with blood.
Antagonistic Skeletal Muscles
Antagonistic muscles are pairs of muscles. The action of one member is opposite to that of the other member. Muscles can contract but they do not have the ability to lengthen (stretch) themselves. They are arranged in pairs such that after one muscle or muscle group contracts, a skeleton transfers the movement to stretch another muscle or muscle group. The pairs of muscles that stretch each other are said to be antagonistic.
Example of an antagonistic muscle pairThe biceps and triceps muscles of the arm are an example of an antagonistic pair. Contraction of the biceps moves the arm toward the body and stretches the triceps. Contraction of the triceps extends the arm and stretches the biceps. In this example the bicep is said to be the flexor while the tricep is the extensor. Extensors are not as strong as flexors.thx:P
Why is it important to rest muscles?
Because that is when the muscle grows. Every time you "workout" you are essentially breaking the muscle apart, while resting it rebuilds to make itself bigger in order to not break the next time, hence getting stronger.
Why is potassium important to the cardiac muscle?
All electrolytes are important to all muscles. In the cells there are sodium/potassium pumps that must be balanced. Some electrolytes are positive and some are negative. The balance (inside the cell vs. outside the cell) causes either contraction or relaxation.
