Answer:

The correct answer is option b. "Alpha eventually replaced by theta".

Explanation:

Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.

Answer:

Spinous process

Explanation:

The rhomboideus minor muscle originates on the <u>spinous processes</u> of vertebrae T2-T5

They attach the superior part of the appendicular skeleton (clavicle, scapula, and humerus) to the axial skeleton (skull, ribs, and vertebral column).

These muscles are sometimes referred to as the appendicular group, since they are primarily involved with movements of part of the appendicular skeleton.

The rhomboideus minor is located deep to the trapezius in the superior part of the back. It inserts on the medial border of the scapula, is innervated by the dorsal scapular nerve its function is to adduct and elevate the scapula.
