What is the term that is used to describe the shape of a muscle?
The terms used to describe the shape of a muscle are; deltoid and rhomboid.
Which two concepts explain how the body produces movement?
The two concepts that explain how the body produces movement are muscle contraction and joint movement. Muscle contraction occurs when muscles shorten or lengthen in response to nerve signals, causing movement. Joint movement allows for the articulation of bones and the range of motion at joints to create different types of movement.
Why does lifting weights make muscles appear larger?
Lifting weights causes tiny tears in muscle fibers, which then repair and grow stronger, resulting in increased muscle size. This process, known as muscle hypertrophy, involves an increase in the size of individual muscle cells, leading to enhanced muscle definition and size. Additionally, increased blood flow to the muscles during exercise can also temporarily swell them, contributing to a larger appearance.
What are the differences between fasciculation and fibrillation?
fasciculation :can be seen by the naked eyescaused by contraction of motor unitsfibrillation: not visible to the naked eyescaused by contraction of individual muscle fibres
The degree of motion at a joint is determined by?
The degree of motion at a joint is determined by the structure of the joint (e.g., the type of joint, presence of cartilage), the surrounding ligaments and tendons, and the range of muscle movement. Joint stability and flexibility also play a role in the degree of motion allowed at a joint.
What is the term to describe the degree to which an individual muscle is lengthen?
Flexibility
A contraction that causes a muscle to lengthen rather than shorten is called?
An eccentric contraction is one that causes a muscle to lengthen.
What is the word for muscular contraction involving muscle movement?
Isotonic contractions are the type that involve muscle movement. This movement is due to a change in length as the muscle fibers shorten or lengthen.
Why do muscles work in antagonistic pairs?
Because muscle can only contracts. The only way for it to lengthen is by having an outside force, ie, another muscle's contraction.
What type of strength development exercise are you performing if the length of your muscle does NOT change?
The type of exercises that does not lengthen the muscle is called isometrics. The strengthening of the muscles is from utilizing range of motion movements.
Do all types of muscle have endomysium covering individual muscle cells?
Yes. All types of muscle have endomysium covering individual muscle cells.
Muscle tissue has four characteristics what are they?
Contractility - the ability of a muscle to shorten. Extensibility - the ability to lengthen. Elasticity - the ability to return to their original shape. And, Excitability - can be triggered by electrical stimulation.
What is the term that is used to describe the shape of a muscle?
The terms used to describe the shape of a muscle are; deltoid and rhomboid.
Which term is used to describe the outer layer of a muscle?
The term used to describe the outer layer of a muscle is the epimysium.
How are individual muscle cells different from the muscle tissue in the bicep?
Muscle cells are smaller than muscle tissues.
Individual muscle cells are called?
muscle fibre
Describe the events of muscle cell contraction?
6 steps in a muscle contraction
