Explanation:
The articular surfaces of the bones are connected by strong collateral ligaments. The best examples of ginglymoid joints are the Interphalangeal joints of the hand and those of the foot and the joint between the humerus and ulna.
Answer:
The correct option is: B) peristalsis
Explanation:
Peristalsis is the involuntary wave-like contractions and relaxations of the smooth muscles of the gastrointestinal tract of the humans.
These alternating contractions and relaxations produces a peristaltic wave that pushes the food down the esophagus of the digestive system. The peristaltic movement prevents the food from moving backwards and pushes the food forward.
Answer:
Dermatology
Explanation:

Surgical dermatology: The dermatologist treats the diseases that affect the skin, hair, and nails through surgical procedures, such as the removal of skin cancer. You have to have a strong stomach because it can get quite gross.
Answer:
Hormones that act on the target cells to increase metabolism are Triiodothyronine (T₃) and Thyroxine (T₄).
Explanation:
The hormones triiodothyronine (T₃) and thyroxine (T₄) are the active forms of thyroid hormone, responsible for increasing cell metabolism.
Both T₃ and T₄are produced by the thyroid gland, in response to the pituitary hormone TSH. T₄ is more abundant but less powerful than T₃
Thyroid hormones are responsible for controlling cell metabolism, since their increase determines an increase in metabolism, and their deficiency slows it down.
The other options are not correct because:
- <em><u>Thyrotropin Releasing Hormone (TRH)</u></em><em> is produced by the hypothalamus to activate the production of TSH in the pituitary gland.</em>
- <em><u>Thyroid Stimulating Hormone (TSH)</u></em><em> is a pituitary hormone in charge of activating the production of T₃ and T₄ in the thyroid.</em>
- <em><u>Adrenocorticotropic Hormone (ACTH)</u></em><em> is produced by the pituitary gland to stimulate the production of hormones in the adrenal cortex.</em>
Answer:
O. Frequency is measured in Hertz (Hz) and is defined as the number of times a wave peaks per second. Frequency is also known as a measure of EEG power.
The amplitude is the height or peak measurement of the cycle measured from time 0 seconds. Amplitude is measured in macro-volts (uV) and reflects EEG control.
Explanation:
EEG frequency is a term commonly used in the medical field to measure the pulse rat of the brain as well as to diagonise epilepsy. This could be found through the abnomalities in the EEG readings when taken.
