Nervous System
This is the physiological name of a nerve cell.
What is a Neuron?
These primarily produce body heat and contract to allow movements in the body and constrict organs and blood vessels.
What are Muscles?
This is the functional units of muscle which shorten when muscles contract.
What is a Sarcomere?
This type of muscle contraction means that the length of a muscle stays the same but the tension changes.
This is described as the prime mover of a contraction.
What is the Agonist Muscle?
Electrical impulse brought into nerve cells.
What is an Action Potential?
This type of muscle tissue is related to the heart and has branching properties due to its appearance under a microscope.
What is Cardiac Muscle Tissue?
Part of a Sarcomere known as the thin filament. Myosin attaches to this during a contraction.
What is Actin?
This type of muscle contraction means that the muscle tension stays the same but the length changes.
This muscle assists the prime mover in performing actions but are not as strong as agonists.
What is a Synergist muscle?
Branch like projections coming off of the body of a nerve cell.
What is a dendrite?
This type of muscle tissue is not striated and is found in various intestinal parts of the body.
What is Smooth Muscle Tissue?
This is a part of a Sarcomere that has thick filament. Resembling a golf club and attaches to Actin.
What is Myosin?
This type of muscle contraction initially increases tension causing the muscle to shorten. (Bicep curl flexion)
What is a Concentric Muscle Contraction?
This muscle is the muscle that performs the opposite action of the prime mover.
What is the Antagonist Muscle?
Long projection coming off of a nerve cell body that sends electric impulse and information out of the cell body.
What is an Axon?
Skeletal Muscles are always twitching and as a result they are always producing this.
What is Body Heat?
A protein that covers the attachment site myosin attaches to. Calcium ions help remove this so that Actin and Myosin can do their jobs.
What is Tropomyosin?
This type of muscle contraction initially decreases the muscle tension and increases the muscle length (bicep curl extension)
What is an Eccentric Contraction?
This muscle is a stabilizer for the joint that muscles contract on and prevents injury during optimal movement of a muscle chain.
What is a Fixator Muscle?
This nervous system consists of the brain and spinal cord and under involuntary control.
What is the Central Nervous System?
This type of muscle tissue is connected to the skeleton and is striated. Muscle movement is voluntary for this type of tissue.
What is Skeletal Muscle Tissue?
This helps sodium ions enter into certain muscle receptors and helps calcium ions remove Tropomyosin.
What is aCh or Acetylcholine?
These are the amount of muscle contractions that exist.
What is 4?
The angle in a muscle decreases during this muscle action.
What is Flexion?
