Study Notes
Antiviral Mechanisms
- Blockers that prevent the formation of the viral replication and transcription complex target key steps in the virus life cycle, disrupting its ability to replicate.
- The primary target of antivirals currently in use often includes viral enzymes or processes critical for replication.
- Ribonucleoprotein complex inhibitors impede virus replication by interfering with the assembly of viral RNA and proteins, preventing the formation of functional virions.
- Interferons function as signaling proteins that enhance the antiviral state of cells, stimulating immune responses and inhibiting viral replication.
- Antimetabolites play a crucial role in inhibiting virus replication by mimicking nucleotide substrates, disrupting nucleic acid synthesis.
Brain Anatomy and Function
- The cortex contains motor and sensory areas, along with higher centers responsible for complex processing and decision-making.
- The thalamus serves as the pain center and acts as a relay station for sensory information, processing and transmitting impulses to the appropriate cortical areas.
- The hypothalamus is responsible for regulating body temperature, acting as the heat regulating center.
- The brainstem contains critical centers for respiration, vasomotor regulation, vomiting, vagal control, and coughing responses.
