Answer: The region of the scapula that does articulate with another bone is the Acromion process
Explanation: The scapula bone is a flat triangular bone located posterior to the thoracic cage. Through the help of scapula muscles, the scapula performs the following movements;
-downward rotation,
- upward rotation
- protraction and
- adduction movements
The acromion process is found at the anterior part of the scapula which articulates with the clavicle bone to form acromioclavicular joint.
Answer:
Medial epicondyle
Explanation:
Little league elbow is an overuse injury caused by stress to the inside of the elbow.
Medial epicondyle is found in the distal end of the humerus bone.
It gives attachment to the ulnar collateral ligament of elbow joint, to the pronator teres, and to a common tendon of origin of some of the flexor muscles of the forearm.
Hitting the medial epicondyle causes a tingling sensation in the ulnar nerve.
Answer:
True!
Explanation:
Carbon monoxide is released from running cars and smoking tobacco. It is, in fact, toxic to humans.
Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
