Answer:
Reflex arc
Explanation:
The reflex arc is a special type of neural pathway which controls the reflex action or the immediate response to the stimulus in the organisms.
The reflex arc involves the receptor, the sensory neuron, the interneuron located in the spinal cord, the motor neuron and the effector's muscle. The action while controlled by the spinal cord also sends signals to the brain.
The reflex arc is an involuntary action that gets activated to the emergency condition like touching the hot plate, cold plate and sudden instance winch require immediate action.
Thus, the reflex arc is the correct answer.
Answer:
Common problems related to female reproductive health include, Endometriosis, Uterine Fibroids, Polycystic Ovary Syndrome and Gynecologic Cancer.
Explanation:
<em>Many problems may potentially affect female reproductive systems, leading to a range of issues...</em>
- Endometriosis describes a condition affecting up to 10% of reproductive-age women. Here, tissue which typically lines the female uterus, grows elsewhere in the ovaries, Fallopian tubes and elsewhere in the abdomen. While some affected experience no symptoms, many report extreme pain that occurs in the lower back, abdomen or pelvis along with infertility in others.
- Uterine fibroids are commonly occurring benign (non-cancerous) tumors made of tissue found in the uterus and muscle cells. They are often accompanied by several symptoms, which affect many women of child-bearing age, such as heavy, painful periods; bleeding between periods, frequent urination, infertility and lower back pain.
- Polycystic Ovary Syndrome is a hormonal disorder where women’s adrenal glands and ovaries produce higher than normal levels of male hormones. This leads to the development of cysts on the ovaries, infertility, acne, pain, extra body hair growth, and irregular periods. Affected women are often at higher risk for the development of heart disease and diabetes.
- Gynecologic Cancer describes any form of cancer occurring in female reproductive organs; they usually begin in the pelvis and include many forms of the disease, including ovarian cancer, cervical cancer and uterine cancer. For instance, uterine cancer begins in the female uterus which is the small organ where babies grow during pregnancy.
Answer:
Microglial cell
Explanation:
The microglial cells are macrophages that are in the central nervous system (brain and spinal cord) protecting it. This cells will phagocytize damaged neurons as when a person has Alzheimer as well as agents that can cause a potential damage to the central nervous system such as the meningitis virus. When the Microglial cells phagocytize they absorb the damaged neuron or antigen and then they destroy it.
It must be widespread, limited in geological time, and distinctive.
