Histology
Histology is the microanatomy method and a branch of biology that studies the anatomy of tissues. It includes viewing tissue in a magnified view under the microscope. Microanatomy also includes the process of study of organs called organology and the study of cells called cytology. Histopathology is a branch of biology that includes microscopic identification of diseased tissue. The field of histology comprises the preparation of the tissues and collection of cells as specimens for examination under the microscope. These processes are done by technicians like histologists, histotechnicians, and biomedical scientists. Histopathology is the diagnosis and research of tissue diseases that require the examination of tissues and/or cells under a microscope. Histopathologists are in charge of determining tissue diagnosis and assisting clinicians in managing a patient's care.
Endocrine System
Human body functions due to the collective work of the organ systems. One of them is the endocrine system. It is a chemical messenger system constituting the hormones directly released by the endocrine glands into the circulatory system. The study of this system is known as endocrinology. The word 'endon' means inside, and 'crine' means secrete, making the word "endocrine."
![**Action Potential Phases Matching Exercise**
In this exercise, you will match the different phases of an action potential depicted in the plot with their correct terms or descriptions. The graph illustrates the changes in membrane potential over time, marked from A to E, each representing a distinct phase in the action potential.
**Graph Description:**
- **Y-Axis (Membrane Potential):** Ranges from -70 mV to +50 mV.
- **X-Axis (Time):** Ranges from 0 to 4 units.
**Phases:**
- **A:** This phase begins at the resting membrane potential (-70 mV) and shows a slight initial increase.
- **B:** A rapid rise in membrane potential, indicating depolarization, reaching a peak of about +50 mV.
- **C:** A sharp decrease from the peak, representing repolarization back toward negative values.
- **D:** A slight overshoot beyond the resting potential, indicating hyperpolarization.
- **E:** Horizontal line indicating the return to the resting membrane potential.
**Matching Terms/Descriptions:**
- **A [] Choose**
- **B [] Choose**
- **C [] Choose**
- **D [] Choose**
- **E [] Choose**
Select the most appropriate term or description for each labeled phase in the provided dropdowns.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F450044ef-db4b-4b73-a24e-98f3627ca204%2F9e7275a4-1130-48dd-b668-d66df3ef8ba5%2Fg9li8_processed.jpeg&w=3840&q=75)
Neurons have the capability of generating and transmitting nerve impulses. The transportation of specific ions across the plasma membrane is responsible for the generation of nerve impulses which directly depends on the activation and inactivation of specific transporter proteins on the plasma membrane.
