What are the differences in appearance on a slide between the endometrium and myometrium? What is the physiological reason for t
andrezito [222]

Answer:

There are big tissue appearance differences between the endometrium and the myometrium. The endometrium is the layer of the intrauterine tissue that is exposed to the intrauterine cavity and is composed of the endometrial epithelium (epithelial cells and glandular cells) , whereas the myometrium is the middle layer composed by muscular cells.

Explanation:

The appearance of the endometrium is a monolayer of polarized epithelial cubic cells and glandular cells, that form the 'luminal' layer of the intrauterine tissue. The cells in the endometrium are prepared to provide nutrients and shelter for the embryo to come. That is why, the endometrium cells are susceptible to hormonal changes throughout the woman's cycle. This hormonal impact makes this tissue grow and be prepared to receive the embryo. If there is no embryo implanted in the endometrium, the hormonal changes also provoke this tissue to 'peel', what is known as menstruation.

On the other hand, the myometrium is composed by smooth muscle cells. These cells are capable of a great flexibility, needed to carry on the pregnancy. The myometrium fulfils a very important role during labour, in which the contraction of the muscle pushes the baby to through the cervix and finally out of the mother's womb. It also expels the placenta after labour. It's structure, flexibility and fast contraction are vital to minimize the blood loss after labour.

Short-term control; released by the duodenum and respond to food in the stomach, resulting in a decrease in appetite.
Lemur [1.5K]

After eating, the gut releases a hormone called cholecystokinin (CCK), which promotes digestion and curbs hunger.

<h3>Is CCK an appetite suppressant?</h3>

Although CCK may only be one of many satiety signals, when given exogenously at pharmacologic levels, it can result in a significant reduction in food intake. Humans' appetites can be decreased by administering exogenous CCK or endogenous CCK released by oral protease inhibitors.

<h3>What use does CCK function?</h3>

The proximal small intestine contains a high concentration of CCK cells, and when food is consumed, the hormone is secreted into the blood. CCK's physiological effects include inducing satiety, regulating stomach emptying, and stimulating pancreatic secretion and gallbladder contraction.

<h3>CCK secretion: What is it?</h3>

A peptide/neurotransmitter secreted by neurons of the central and peripheral nervous systems, cholecystokinin (CCK) is a hormone released by the I-cells of the upper small intestine in response to fat, protein, and some nonnutrients.

Greater decreases in overall brain volume in later adulthood is associated with ________________ in cognitive abilities and cogn
TEA [102]

Greater decreases in overall brain volume in later adulthood is associated with an unclear exact relationship in cognitive abilities and cognitive functioning.

<h3>How brain changes in late adulthood?</h3>

The brain's size reaches roughly 90% of its adult volume by the time a child is six years old. The brain begins to contract in our 30s and 40s, and by the time we reach our 60s, the brain is contracting even more rapidly. The brain begins to change in appearance, just like wrinkles and gray hair do later in life.

The brain actually shrinks and its overall mass decreases as adults. There are decreases in some neurotransmitters as well, including dopamine and acetylcholine. Loss of memory for recent events, familiar names, and familiar duties is the first sign of Alzheimer's disease. In old age, general knowledge memory does not deteriorate. There has been a deterioration in episodic and event memory.
