Answer:
According to the case history, Mrs.Wharton is a 59-year-old woman who presented in the dermatologist's office with a complaint of changes in a mole or a<u> nevus.</u>
Explanation:
The correct answer to complete the sentence is the term "nevus". A nevus (plural:nevi) is the medical term for the word mole, which in most occasions is what patients will use to describe the condition. A nevus or mole are the product of a collection of colored cells, and are very common among people, with the average of 10 to 40 nevi per person. Although most nevus are harmless in their nature, it is important for everyone that has one to check them regularly, and in the case that the person sees a change in the appearance of the nevus he/she should go to the doctor's office for a medical examination, just like Mrs. Wharton did.
Answer:
The answer is D
Number of motor units recruited
Explanation:
The force a muscle generates is dependent on the length of the muscle and its velocity which is shortened.
A motor unit is the grouping of muscle fibers supplying nerves by the neuron and consists of the motor neuron.
The number of muscle fibers within a motor unit varies, and is a function of the muscle’s ability for accurate and refined motion.
Precision can be determined to be inversely proportional to the size of the motor unit. As a result, small motor units can exercise greater precision of movement compared to larger motor units. For example, thigh muscles which are responsible for large powerful movements, can have a thousand fibers in each unit, while eye muscles which requires small precise movements, might only have about ten.
Groups of motor units are supplied with nerves to coordinate contraction of a whole muscle and generate appropriate movement; all of the motor units within a muscle are referred to as a motor pool.
As a result, the number of motor units with are recruited will facilitate the maximum amount of tension that allows the student keep his arm extended in place under the increasing weight of the books.
