A build up of lactic acid in the muscles and a lack of ATP.

Leads to the enlargement of skeletal muscle are unable to contract

How many skeletal muscles does the body have

Aerobic excerise can cause the following except:

A specialized nerve that transmits a impore to musical causing contractions

A specialized point of contract between a nerve ending and the muscle fiber it contracts.

The combination of the neuron and the skeletal muscluar it stimulates

Graded responds are :

Graded responses can be produced all of the following ways except:

Single contractions of muscles fibers caused by rapid delievery of the nerves

Sustained and stecely muscle contractions caused by a series of stimuli coming in a muscle in a rapid sucession

Microfilments shorter and produce movements at a joint The tension applied is held constrast until provides indevices and muscle enlargement.

Mersce relaxes and contractions in which muscles do not shorten, movements is not occurring.

When a muscle is served or damaged it nerves supply will do which of the following except:

Attachment to the bone that remains relatively station and fixed when movement at the joint occurs.

Attachs muscle to bone

Small sacs filled with fluid that in located between some tendons and underlining bone.

Point of an attachment of bone that moves when a muscle is contracted.

Plasma membrane of the muscle cell

Cytoplasm of a muscle cell

The thick protein of myofilment

The thin protein of the myofilament

Contractic units made up myosin at actin

Ready contracliy muscle cells that are grouped

Long ribbon like organelles in the cytol cell of a muscle cell and make up the muscle fibers

A group of muscle cell

Straited and voluntary. Makes up to 40-50% of body weight.

Found in the stomach and intestines

Muscles' ability to increase in length
