Study Notes
Introduction to Pathophysiology and Cellular Basis of Disease
- Explores how diseases arise through physiological changes at the cellular level.
- Emphasizes understanding of normal cellular functions to comprehend disease mechanisms.
- Mechanisms include inflammation, infection, and genetic alterations affecting cell behavior.
Maintaining Cellular Function
- Cells rely on homeostasis for optimal functioning, adapting to internal and external changes.
- Key processes include metabolism, signal transduction, and cell communication.
- Intracellular and extracellular fluid balance is crucial for cellular activities.
Relationship between ECF and ICF
- Extracellular fluid (ECF) and intracellular fluid (ICF) maintain a dynamic equilibrium.
- ECF surrounds cells providing nutrients, while ICF facilitates metabolic processes within cells.
- Proper electrolyte distribution between ECF and ICF is vital for cell function.
ECF Electrolyte Balance
- Fluid and electrolyte balance regulates osmotic pressure and cell volume.
- Major electrolytes include sodium (important for nerve impulse transmission) and potassium (crucial for muscle function).
- Imbalance can lead to conditions such as dehydration or edema.
Acid-Base Balance
- The body maintains pH balance through buffer systems, respiratory control, and renal function.
- Normal blood pH ranges from 7.35 to 7.45, critical for enzyme function.
- Disorders like acidosis or alkalosis disrupt metabolic processes and homeostasis.
Normal Function of the Nervous System
- Nervous system comprises central nervous system (CNS) and peripheral nervous system (PNS).
- Functions include sensory perception, motor control, and homeostasis regulation.
- Neural communication relies on neurotransmitters and synaptic transmission.
Peripheral Nervous System
- Divided into somatic and autonomic nervous systems; somatic controls voluntary movement, while autonomic regulates involuntary functions.
- Autonomic nervous system further splits into sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) pathways.
- Peripheral nerves connect CNS to limbs and organs, facilitating communication and reflexes.
Autonomic Nervous System
- Manages automatic body functions, including heart rate, digestion, and respiratory rate.
- Sympathetic pathways prepare body for stress, while parasympathetic restores body to resting state.
- Balance between sympathetic and parasympathetic activity is essential for homeostasis.
Endocrine System
- Comprises glands that secrete hormones, regulating various bodily functions including metabolism, growth, and reproduction.
- Hormonal signaling influences long-term physiological changes compared to the rapid responses of the nervous system.
- Major glands include pituitary, thyroid, adrenal, and pancreas, each having unique roles in homeostasis and health.
