The hormones affected by oophorectomy are estrogen and <u>progesterone</u>.
The gland affected by oophorectomy is the pituitary gland.
<u>Explanation:</u>
- Oophorectomy is a procedure to remove one or both ovaries. It is done to prevent ovarian cancer or endometriosis.
- The ovaries make most of the body's estrogen. when ovaries are removed there will be a sudden drop in the estrogen levels. To tackle it, estrogen therapy is given.
- Due to the disruption of the Hypothalamus ovary connection. the Pituitary gland produces more Follicle-stimulating hormone (LSH), Luteinizing hormone (LH), Gonadotropins.
Answer:
For a contraction to occur there must first be a stimulation of the muscle in the form of an impulse (action potential) from a motor neuron (nerve that connects to muscle). Note that one motor neuron does not stimulate the entire muscle but only a number of muscle fibres within a muscle.
Explanation:
Terminal buttons.
Explanation:
Neurons are longest animal cell that serve as the basic unit of their nervous system.
The neuron is divided into two parts-
Cyton: It is the cell body of the neuron. It has projection extending from the cytoplasm that receive signals called dendrites.
Axon: It is a long process extending from the cyton that carries the impulse from cell body to end of neuron. The axon terminate at knob like structures called terminal button . These release neurotransmitter and are rich in mitochondria.
Atherosclerosis refers to build up of plaques in blood vessels. This leads to obstruction of blood flow which results in mortality. The plaque development occurs at endothelial cells. This research by Dai, et al., 2004 aims to understand the functional and non functional physical features of endothelial cells in condition of specific blood flow pattern. They utilized 3D flow analysis to characterize flow patterns and used "athero-prone" and "athero-protective" waveforms. These were found to represent shear stress on carotid artery that could easily develop or resist formation of atherosclerotic lesion.
The analysis of results were done via cDNA microarrays for gene expression. The effect of waveforms was also checked through different parameters like expression and localization of junctional proteins, expression of adhesion molecules and expression of proinflammatory cytokines etc. The researchers conclude presence of phenotypic alteration depending upon shear stress in atherosclerosis sensitive and resistant human arterial geometries.

Answer:
The cell could not make ATP.
Explanation:
Glycolysis may be defined as the process in which a glucose molecule is broken down into the two molecules of the pyruvate. Pyruvate is used to produce energy through various pathways that depends upon the availability of the oxygen. However when the glycolysis in blocked and the pyruvate is not formed, then the cells would not be able to use either the fermentation or aerobic respiration or the perform citric acid cycle. So the cell does not make any ATP.
