Muscular System

Decreases

It's not really a toxin per se, it's called lactic acid.

Tendons connect muscle to muscle and also muscle to bone.

An average adult male is made up of 42% voluntary muscle, an average adult female is made up of 36% voluntary muscle (in terms of total body mass).

lower trapezius, serratus anterior

the chemical is glucose.

skeletal muscles

Only striated muscles have sarcomeres , Skeletal and Cardiac muscles have sarcomeres. As for smooth muscles they doesnt have sarcomeres , since the Z lines are attached to dense bodies

The primary muscles responsible for moving the mandible side to side are the lateral pterygoid and the medial pterygoid muscles. The lateral pterygoid muscle facilitates the protrusion and lateral movement of the mandible, while the medial pterygoid assists in elevating the mandible and also contributes to lateral movements. Together, these muscles enable the grinding motion necessary for chewing.

When your muscles burn, it means you have gone from aerobic respiration to anaerobic respiration. Aerobic respiration, or cellular respiration, uses oxygen to produce the ATP your muscles need to function. When you run long enough or fast enough, however, your muscles run out of oxygen and must turn to anaerobic respiration, which also produces ATP but has lactic acid as a waste product. It is the lactic acid that makes your muscles burn and makes them sore afterwards and the next day.

The term skeletal means that they affect the the bones of the skeleton. They are called striated as the muscle fibers (also called cells) show the contracting units called sacromeres as lines in the cell as seen under the microscope. They are voluntary as you have control over them using your nervous system.

First of all, the digestive system is full of organs, not muscles. Mouth- mechanically breaks down food by churning and cutting. Esophagus- the long tube the links to the liver, and passes the food down to then liver. Stomach- the holding place for the food for 4-6 hours. The food is then chemically broken down. Pancreas- functions to produce enzymes to send all over the body. Liver- produces bile Gall bladder- stores bile Duodenum- the small tube that links the small intestine and stomach. Small intestine- the 20 ft. Long tube that food passes through to get to the large intestine. Large intestine- the 4ft long tube that passes food to the rectum. Rectum- the place that stores food and waste. Anus- the opening and the end of the rectum that eliminates waste.

Subscapularis

These muscles all have a ligament of insertion which is called the patellar ligament. This ligament inserts to the tibial tuberosity.

cardiac muscle

Cardiac muscle tissue, like skeletal and smooth muscle tissue, can undergo hypertrophy.
Unlike both smooth and skeletal muscle, cardiac muscles have cells that branch.

Glucose and Oxygen. If it is an aerobic reaction then the formula will be; 60^2 + C^6O^12H^12 = 6H^2O + 6^CO^2 + 38ATP

The muscle is said to undergo Fatigue.

Neuromuscular junction (NMJ)

all muscles pull on bones to create movement, since muscles are contractile and bone is rigid. the muscle attaches to the bone via the tendon.

the smooth tissue of the liver is the kidney stone of the heart. small intestine and the large intesting produce smooth tissues and the waste products are know as th lungs.
