During a muscle contraction, the muscle cell membrane is?

The term blind sport denotes the small gap in the visual field. It  is the location on the retina known as the optic disk where the optic nerve fiber exit the back of the eye. This small gap in the visual field is caused because there are no cones or rods at this point on the retina.  So, the correct answer is B: It's is an area of the retina where there are no rods or cones.

Answer:

The correct answer is True.

It is false.  

It is an exercise used in improving flexibility, stability and core strength and mobility of the spine. This training can be performed in many ways that allowed an individual to progress, challenge and perform what is suitable or work best for you.

Further Explanation

The trunk is very essential component of any motion that the body performs. The truck muscles aid movement in individual, maintain body balance and give stability to the body. The body won’t be able to function properly without a strong truck. Enhancing the truck mobility with rotational exercise like this can provide body fitness. It can also provide sport performance benefit.

Truck rotation is the kind of movement which involves thoracic, lumbar vertebrate and muscles which include

• Internal oblique – which helps to turn and rotate the trunk
• External oblique – this is the side abs that helps in rotating the trunk
• Rectus abdominis – it flexes the spine and torso
• Lumbar multifidus- it helps to stabilize the spine
• Transverse abdominis- it helps to stabilize both the pelvis and low back.

Truck rotation is an exercise that is mostly used in sporting activities. It is also used during individual functioning daily activities. Truck rotation improves strength, function as well as the mobility of the truck muscles.

How to perform truck rotation safely and effectively  

• You have start in a supine position on a mat.
• Bent your knees and feet flat on the floor
• Your upper body must be maintained firmly against the floor
• Stretch out your arms and press into the floor, this will help you to balance during the movement.

The statement 'trunk rotation is the most common static flexibility assessment' is FALSE.

What is flexibility?

Flexibility can be defined as the ability to move different joints through a pain-free range of motions.

• The best method to assess flexibility is by measuring the degrees of rotation of the joints.

• This method can be used in virtually any moveable joint whose flexibility we can determine.

In conclusion, the statement 'trunk rotation is the most common static flexibility assessment' is FALSE.
