Flexion
Adduction
Extension
Abduction
The Correct Answer is D
A. Flexion refers to a bending movement that decreases the angle between two body parts, such as bending the knee or elbow, but it does not involve lateral movement away from the body's midline.
B. Adduction is the movement of a body part toward the midline of the body, opposite of what the question describes.
C. Extension refers to a straightening movement that increases the angle between two body parts, such as straightening the arm or leg, but again does not involve lateral movement.
D. Abduction is the correct term for moving a limb or body part away from the midline of the body. In this case, it refers to the lateral movement of the leg away from the body's midline.

Correct Answer is C
Explanation
A. Peristalsis, the wave-like contraction of the digestive tract, is typically decreased during sympathetic stimulation. The sympathetic nervous system tends to slow digestive processes as the body prioritizes "fight-or-flight" responses.
B. Bladder tone is typically decreased by sympathetic stimulation. The sympathetic nervous system causes relaxation of the bladder, inhibiting urination during stressful situations.
C. Heart rate increases with sympathetic stimulation. The sympathetic nervous system prepares the body for action by increasing heart rate, enhancing blood flow to muscles, and increasing energy levels.
D. Saliva production decreases with sympathetic stimulation. The body reduces non-essential functions such as salivation during stress, focusing energy on immediate survival functions.
Correct Answer is A
Explanation
A. Oogenesis is the process of meiosis that leads to the formation of egg cells (ova). It involves the reduction of chromosome number by half, resulting in haploid egg cells, which are essential for reproduction.
B. The ovaries are the organs where oogenesis takes place, but they are not the process itself. They contain the oocytes and other structures involved in female reproduction.
C. Oocytes are the immature egg cells present in the ovaries before they undergo meiosis and maturation during oogenesis. They are the precursors to mature egg cells but do not describe the process.
D. Ovulation is the release of a mature egg cell from the ovary, which occurs after oogenesis is complete and the egg is ready for fertilization, but it is not the process of meiosis itself.
