Study Notes
Left Ventricular Hypertrophy
- Occurs as an adaptation in the heart to manage increased workload.
Atrophy Characteristics
- Primary characteristic of atrophy is decrease in cell size and function.
Uterine Hypertrophy
- The main cause of hypertrophy in the uterus is increased estrogen levels during pregnancy.
Hyperplasia Characteristics
- Key characteristic of hyperplasia is an increase in the number of cells, often in response to a stimulus.
Atrophy Types
- Type of atrophy associated with inadequate nutrition and cachexia is termed nutritional atrophy.
Results of Hypertrophy
- Main result of hypertrophy is an increase in tissue or organ size, enhancing functional capacity.
Reversible Cell Change
- Adaptation involving reversible change from one adult cell type to another is known as metaplasia.
Workload-Related Atrophy
- Primary cause of atrophy related to decreased workload is disuse, leading to muscle atrophy.
Cellular Adaptation Processes
- Cells modulate their environment using adaptive processes to potentially escape injury and maintain homeostasis.
Biochemical Mechanisms of Atrophy
- Biochemical mechanisms associated with atrophy include decreased protein synthesis, increased protein degradation, and activated autophagy.
