3. The following is true regarding male breast?

4. Female breast lies in anterior thoracic wall in superficial fascia with Strands of fibrous tissue called suspensory ligaments which connect dermis to fascia and help maintain protuberance of young breast

True

False

5. After parturition oestrogen & progesterone decreases and prolactin produced by hypophysis result in commencement of true milk distends alveoli and milk passes to ducts secretions and sucking, nerves of nipple result in afferent impulses which causes oxytoxin production from hypothalamus.
