Answer 1

Here are the answers to your questions:

**Question 1:**
**Hyperextension**
Explanation: Hyperextension refers to the movement that straightens a joint beyond its normal range.

**Question 2:**
**Horizontal flexion**
Explanation: Moving the arm parallel to the floor and across the body describes horizontal flexion.

**Question 3:**
**True**
Explanation: Understanding how the elbow joint works helps players adjust their form and avoid injury.

**Question 4:**
**Movements of rotation**
Explanation: The transverse plane is associated with rotational movements of the body.

**Question 5:**
**206**
Explanation: The adult human body typically has 206 bones.

**Question 6:**
**Butterfly**
Explanation: Butterfly is not a recognized type of joint in the body.

**Question 7:**
**Biceps**
Explanation: The biceps muscle is responsible for pulling on the radius during arm flexion.

**Question 8:**
**Accountability**
Explanation: Accountability is not considered an essential element of a muscle, while elasticity, plasticity, and excitability are.

**Question 9:**
**The ability to contract and develop tension**
Explanation: Contractility refers to the muscle's ability to shorten and generate tension.

**Question 10:**
**Muscles**
Explanation: Muscles are responsible for producing the force necessary to move the body.

**Question 11:**
**Nodding the head**
Explanation: Nodding the head is an example of a first-class lever in the body, where the fulcrum is between the effort and the load.

**Question 12:**
**Standing on tip toes**
Explanation: Standing on tiptoes is an example of a second-class lever where the load is between the fulcrum and the effort.

**Question 13:**
**The rotational effect of force**
Explanation: Torque is defined as the rotational effect of a force applied to a lever.

**Question 14:**
**Base of support**
Explanation: The base of support refers to the point of contact with an immovable object and the body.

**Question 15:**
**Inconsistent force variance**
Explanation: Inconsistent force variance is not a benefit of strength training. The other options are indeed benefits.
