Label the features of the stomach and nearby regions in this frontal section of a cadaver (anterior view)
Fantom [35]
1- Pyloric sphincter
2-Duodenum
3- Bile duct
4-Pancreatic duct
5-Esophagus
6-Lower esophageal sphincter
7-Fundus of stomach
8- Cardia
9-Body of stomach
10-Pyloric part

The <span>esophagus(5) connects to the stomach.</span>
<span> The food passes,from the pharynx, to the esophagus, to the stomach. This process is aided by peristaltic movements done by esophagus muscles.
This organ contains two sphincters:</span><span>the upper and the lower esophageal sphincter.
 
</span>The stomach is divided into four parts:
<span><span>1-The cardia (8) - this part is connected to  the esophagus and its where  the epithelium changes from stratified squamous to columnar.
In this region is the lower esophageal sphincter (6).

</span>2--The fundus(7)- It's formed by the upper curvature of the stomach.

3- the body(9)- is the main part; and the biggest

4-The pylorus/</span><span> Pyloric part (10) - is the lower region. This part is connected to the small intestine, the duodenum. In this region there is a </span>
strong ring of muscle called the (<span>1) Pyloric sphincter.


In the first part of the duodenum there is a connection with a duct that comes from the pancreas -4-</span>Pancreatic duct .

A scientist notices that when she adds a small, water-soluble molecule to a dish of cells, the cells turn off transcription of a
Lelechka [254]

Answer:

Enzyme-linked

Explanation:

The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).

Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
