There is an opening of the parotid duct on the mucosa of the maxillary second molar.

Shape: upper and lower sides, the upper side is called the dorsum of the tongue.

Parotid glands (largest pair of oral glands), triangular wedge-shaped Located in front of the auricle.

parotid duct

submandibular gland

sublingual gland

Connected with the nasal cavity, oral cavity, and throat cavity.

According to the adjacency of its anterior wall, it is divided into three parts: nasopharynx, oropharynx and hypopharynx.

The three strictures are areas where foreign bodies in the esophagus are likely to remain, and are also prone to inflammation and tumors.

The pylorus can be divided into the pyloric sinus on the left and the pyloric canal on the right

The pylorus and the lesser curvature of the stomach are common sites for gastric ulcers

The upper part, also known as the duodenal bulb, Is a common site for duodenal ulcers

Descending part, descends along the right side of lumbar vertebrae 1 to 3, The great duodenal papilla is the common opening of the common bile duct and pancreatic duct. The duodenal papilla is the opening of the accessory pancreatic duct

Horizontal part, lower part: in front of the third lumbar vertebra

Ascending part, left side of the second lumbar vertebra, The duodenal suspensory ligament is an important landmark for identifying the starting point of the jejunum during surgery.

Return to the near side of the court 2/5, color pink

It accounts for 3/5 of the long side of the total length and is grayish pink in color.

Colonic bands, colonic pouches and intestinal fat tags

It is the beginning of the large intestine, located in the right iliac fossa, in the shape of a blind sac.

The terminal ileum protrudes into the cecum, preventing the contents of the large intestine from flowing back into the ileum.

The intersection of the middle and outer 1/3 of the line connecting the umbilicus and the right anterior superior iliac spine is McFarland's point.

Ascending colon, transverse colon, descending colon, sigmoid colon

The upper end is at the level of the third sacral vertebra, and the lower end ends at the pelvic diaphragm.

2 curvatures: sacral curvature, convex backward Perineal curvature, convex forward

The intestinal cavity in the lower rectum is significantly enlarged, called the rectal ampulla

Dropping medicine, lying on left side, curled up

anal column anal valve anal sinus

dentate line Hemorrhoid rings (anal comb) white line

Wedge-shaped, with the right end rounded, blunt and thick, and the left end flat and thin. It can be divided into upper and lower sides and front and rear edges. The top of the liver is close to the diaphragm and is called the diaphragm surface. The lower surface is adjacent to the organs and is called the dirty surface. There are H-shaped grooves on the dirty surface, a longitudinal groove on the left, a longitudinal groove on the right, and a transverse groove. There is a fissure in the front part of the left longitudinal groove, the round ligament of the liver, which passes through and makes the liver hang under the diaphragm. The posterior part is called the ligamentous venous fissure, which accommodates the ligamentum venosus, and the anterior part of the right longitudinal groove is the gallbladder fossa, which accommodates the gallbladder. The posterior part is the vena cava groove, through which the inferior vena cava passes. The transverse groove is called the hepatic portal, which houses the proper hepatic artery, hepatic portal vein, and hepatic duct.

Most of them are located in the right rib area and supraventral area, and a small part is located in the left rib area.

The upper boundary is the intersection of the right midclavicular line and the fifth rib, the intersection of the anterior midline and the xiphithoracic union, and the intersection of the left midclavicular line and the fifth intercostal space. Lower boundary, the right side is roughly consistent with the right costal arch, the middle part extends about 3cm below the xiphoid process, and the left side is covered by the costal arch.

Gallbladder, a sac-like organ that stores and concentrates bile, can be divided into gallbladder base, gallbladder body, gallbladder neck, and cystic duct
