Study Notes
Physiology in the Medical Field
- Physiology studies the functions and processes of living organisms, focusing on how systems within the body work both individually and together.
- It explores various bodily systems, including respiratory, circulatory, digestive, and endocrine systems.
- Understanding physiology is crucial for diagnosing and treating medical conditions effectively.
Importance of Physiology in Dentistry
- Physiology is essential in dentistry to understand oral health dynamics, including the function of teeth and gums.
- Knowledge of physiological processes aids in managing pain and inflammation during dental procedures.
- Physiological principles guide the development of treatment plans and the use of anesthesia in dental practices.
Central Nervous System Components
- The central nervous system (CNS) consists of the brain and spinal cord.
- It serves as the primary control center for processing sensory information and coordinating responses.
Protection of the Central Nervous System
- The CNS is protected by bony structures—specifically the skull encasing the brain and the vertebral column surrounding the spinal cord.
- Meninges, which are three protective membranes (dura mater, arachnoid mater, pia mater), also safeguard the CNS.
- Cerebrospinal fluid acts as a cushioning agent, providing further protection from physical impact and facilitating nutrient exchange.
Significance of Inability of CNS Cells to Divide
- Cells in the central nervous system, such as neurons, typically do not divide after development, limiting regeneration capabilities.
- This characteristic is significant as it impacts recovery from injuries or degenerative diseases affecting the CNS.
- The inability to replace damaged neurons complicates treatment strategies for conditions like spinal cord injuries and neurodegenerative disorders.
