linea alba

Examples of linea alba in the following topics:

• Anterior Muscles

  • Toward the midline, the muscles form aponeuroses, which merge into the linea alba.
  • Attachments – Originates from the lower ribs and attaches to the pelvis, forming an aponeurosis toward the midline and linea alba.
  • Attaches to the lower ribs and forms an aponeurosis toward the midline and linea alba.
  • Attachments - Originates from the lower ribs, thoracolumbar fascia, and pelvis, forming an aponeurosis toward the midline and linea alba.
  • Attachments – Originates from the pubis and attaches to the linea alba.

• Anatomical Changes

  • These signs include the presence of human chorionic gonadotropin (hCG) in the blood and urine, missed menstrual period, implantation bleeding (occurs at implantation of the embryo in the uterus during the third or fourth week after last menstrual period), increased basal body temperature sustained for over 2 weeks after ovulation, Chadwick's sign (darkening of the cervix, vagina, and vulva), Goodell's sign (softening of the vaginal portion of the cervix), Hegar's sign (softening of the uterus isthmus), and pigmentation of the linea alba (called linea nigra), which is darkening of the skin in a midline of the abdomen.

• Pubis

  • (1) sacrum, (2) ilium, (3) ischium, (4) pubis: 4a-body; 4b-superior ramus; 4c-inferior ramus, (5) pubic symphisis, (6) acetabulum, (7) obturator foramen, (8) coccyx, (red dotted line) linea terminalis.

• Lumbar Plexus

  • Obturator nerve: Leaves the lumbar plexus and descends behind the psoas major on its medial side, follows the linea terminalis into the lesser pelvis, then finally leaves the pelvic area through the obturator canal.

• Uterus

  • The fundus does not surpass the linea terminalis.
