What joint actions occurring in a lateral raise during the concentric and eccentric phase?
To see eccentric contraction, look at the biceps curl with flexion around the elbow. As you lower a weight, you are working against resistance, letting the joint angle increase to lower that object under your control.The opposite is the concentric contraction were the arm is flexed upward to decrease the angle at the elbow.
What is the muscle group that stabilises the knee joint during the stance phase?
Quadriceps femoris
Why do not action potentials occur during the repolarization phase?
It has to do with what types of channels are open during this phase. In the repolarization phase the number of potassium channels are increased and the number of sodium channels are decreased. This allows for action potentials to not occur. Otherwise, the action potentials would add up and produce tetany.
What is an afterhyperpolarization?
An afterhyperpolarization is the hyperpolarizing phase of a neuron's action potential.
What is the phase in the action potential that immediately follows repolarisation?
After the falling phase or repolarization the membrane potential goes below its normal resting potential.This phase is often called undershoot, or phase of hyperpolarization.

What is the joint action during the eccentric phase of a biceps curl?
A concentric movement would be flexing the elbow and curling a dumbbell towards the shoulder, an eccentric contraction would be the opposite movement ie bringing the dumbbell back down towards the thigh.
When performing push ups the concentric phase is?
when you push yourself away from the floor, the lowering phase is the eccentric phase concentric = shortening of muscles - i like to think of this as when the muscles are "working" eccentric = lengthening of muscles - i like to think of this as when the opposite muscles would work to perform the action - e.g. when biceps brachii is eccentric in a bicep curl it is on the lowering phase (i.e. elbow extension - usually performed by triceps brachii)
What is the joint action during the concentric phase of reverse fly?
horizontal abduction
What phase is the muscle the strongest eccentric concentric or isometric?
Isometric
Swallowing a reflex action?
Yes, swallowing is a reflex action of which there are three phases. These are the oral phase, the pharyngeal phase and the esophageal phase.
What muscles is contracting eccentrically during the lowering phase of lateral raise?
medial deltoids
What type of malignant melanoma does not display radial or lateral growth?
With the exception of the nodular variety of melanoma, there is often a phase of radial or lateral growth associated with these tumors.
Ten resistance training exercises and describe which phase of the exercise is the eccentric concentricisometric phase of the movement at which phase is the muscle the strongest why?
There are many exercises that you can use. Go through some of the ones online and see if they will meet your needs.
Is Eccentric muscle training safe?
Is lowering the weight during a workout important? Eccentric contractions are the lowering ( lengthening technically) phase of an exercise. So lowering the weight after a bicep curl or bench press is the the eccentric phase. On a lat pulldown it’s actually when you are bringing the bar back up. The eccentric phase causes much of the muscle soreness we feel the next day but it also leads to small tears in the muscle cells which leads to one part of muscle growth. So they are beneficial parts of the exercise.
What is Pharmaceutical phase of drug action?
Pharmaceutical phase of drug action is the first of the three phases to drug action. It includes the disintegration of the dosage form as well as the dissolution of the drug
The second phase in mouth opening and movement of the temporomandibular joint is?
Gliding
