Part of a feedback system that detects changes in the environment (stimuli).

Control Center (Homeostasis)

Processes information from the receptor and determines the appropriate response.

Effector (Homeostasis)

Carries out the response to restore homeostasis, regulated by feedback.

Study Notes

Cancer Staging

  • Overview: Cancer staging is a critical process that determines the extent of cancer in the body, including tumor size, invasion depth, and spread to other regions. Accurate staging informs treatment decisions and helps predict patient prognosis.
  • Staging Criteria: Evaluates tumor size, local invasion, and metastasis. Involves assessment of primary tumor characteristics and regional lymph node involvement.
  • Stage Definitions:
    • Stage 1: Tumor confined to its organ of origin.
    • Stage 2: Tumor is locally invasive but has not spread to regional structures.
    • Stage 3: Tumor has advanced to regional structures (e.g., lymph nodes).
    • Stage 4: Tumor has metastasized to distant sites in the body.
  • Prognosis: Staging significantly influences prognosis; earlier stages generally correlate with better outcomes. Treatment options vary based on stage, impacting survival rates and quality of life. Surgical margins must be adequate to ensure complete removal of the tumor for effective treatment.

Tumor Classification

  • Overview: Tumor classification categorizes tumors based on their characteristics, origin, and behavior. It distinguishes between benign and malignant tumors, which differ in growth patterns, invasiveness, differentiation, and potential for metastasis.
  • Benign Tumors: Named according to the tissue of origin with the suffix "-oma." Examples: Lipoma (fat), Leiomyoma (smooth muscle).
    • Characteristics: Slow growth, well-defined capsule, not invasive, well differentiated, low mitotic index, does not metastasize.
  • Malignant Tumors:
    • Types include: Carcinomas (malignant epithelial tumors), Example: Adenocarcinoma (ducts or glands), Sarcomas (malignant connective tissue tumors).
