transverse plane

Examples of transverse plane in the following topics:

• Body Planes and Sections

  • There are three basic reference planes used in anatomy: the sagittal plane, the coronal plane, and the transverse plane.
  • The transverse plane (axial or X-Z plane) divides the body into superior and inferior (head and tail) portions.
  • A longitudinal plane is any plane perpendicular to the transverse plane, while parasaggital planes are parallel to the saggital plane.
  • The coronal plane, the sagittal plane, and the parasaggital planes are examples of longitudinal planes.
  • There are three basic planes in zoological anatomy: sagittal, coronal, and transverse.

• Abdominopelvic Regions

  • These quadrants are defined by the intersection of the saggital plane with the umbilical plane (the transverse plane through the navel).
  • The right upper quadrant contains the right portion of the liver, the gallbladder, right kidney, a small portion of the stomach, the duodenum, the head of the pancreas, portions of the ascending and transverse colon, and parts of small intestine.
  • The left upper quadrant is the location of the left portion of the liver, part of the stomach, the pancreas, left kidney, spleen, portions of the transverse and descending colon, and parts of the small intestine.
  • These divisions are marked by two parasagittal and two transverse planes centered around the navel.
  • It also contains the transverse colon (the section between the ascending and descending colons) and the bottom portions of both the left and right kidney.

• Parts of the Cerebellum

  • Superior view of an "unrolled" cerebellum, placing the vermis in one plane.
  • Transverse section of a cerebellar folium, showing principal cell types and connections.

• Uterus

  • These ligaments include the pubocervical, transverse, cervical, cardinal, and uterosacral ligaments.
  • The uterus is in the middle of the pelvic cavity in frontal plane (due to ligamentum latum uteri).

• Digestive System Development

  • The midgut is the lower duodenum, to the first two-thirds of the transverse colon lower duodenum, jejunum, ileum, cecum, appendix, ascending colon, and first two-thirds of the transverse colon.
  • The hindgut is the last third of the transverse colon, descending colon, rectum, and upper part of the anal canal.

• Arches of the Feet

  • The two longitudinal arches and a transverse arch are maintained by the interlocking shapes of the foot bones, strong ligaments, and pulling muscles during activity.
  • In addition to the longitudinal arches, the foot presents a series of transverse arches.
  • The transverse arches are strengthened by the interosseous, plantar, and dorsal ligaments, by the short muscles of the first and fifth toes (especially the transverse head of the Adductor hallucis), and by the Peronæus longus, whose tendon stretches across between the piers of the arches.

• Cervical Plexus

  • They are located laterally to the transverse processes between prevertebral muscles from the medial side and anteriolateral to the m. scalenus and m. levator scapulae.
  • Transverse cervical nerve - The transverse cervical nerve (superficial cervical or cutaneous cervical) arises from the second and third cervical nerves, turns around the posterior border of the sternocleidomastoideus about its middle, and, passing obliquely forward beneath the external jugular vein to the anterior border of the muscle, it perforates the deep cervical fascia and divides beneath the platysma into ascending and descending branches, which are distributed to the antero-lateral parts of the neck.

• Parts of a Vertebra

  • The two transverse process project laterally from the join between the pedicle and lamina and also serve as an attachment point for muscles and ligaments of the back.
  • In conjunction with the vertebral body the transverse processes articulate with ribs.

• Muscular Arteries

  • Transverse section of the human spleen, showing the distribution of the splenic artery and its branches

• Anatomy of the Large Intestine

  • From here it continues up the abdomen (ascending colon), then across the width of the abdominal cavity (transverse colon), and then it turns down (descending colon), continuing to its endpoint at the anus (sigmoid colon to rectum to anus) .
  • Scheme of large intestine, with colon marked: cecum; (1) ascending colon; (2) transverse colon; (3) descending colon; (4) sigmoid colon; rectum and anus.
