POST-TRANSCRIPTIONAL GENE SILENCING PATHWAYS
Post-transcriptional gene silencing (PTGS) refers to the process by which gene expression is suppressed at the RNA level. This mechanism plays a crucial role in regulating gene expression and maintaining cellular homeostasis. PTGS pathways involve several key molecular processes, including…
PRINCIPLES AND ORGANIZATION OF SIGNAL TRANSDUCTION PATHWAYS
Signal transduction pathways are essential mechanisms that cells use to communicate with their environment and coordinate their responses to various stimuli. These pathways are crucial for maintaining cellular homeostasis, regulating growth and development, and responding to external signals such as…
GENERAL SENSORY PATHWAYS OF THE TRUNK AND LIMBS
The general sensory pathways for the trunk and limbs involve three main components: receptors, ascending pathways, and sensory cortex. Receptors: Specialized nerve endings called receptors are distributed throughout the skin, muscles, tendons, and other tissues in the trunk and limbs.…
EAR AND AUDITORY PATHWAYS
Ear Structures Explained The ear is a complex sensory organ responsible for hearing and maintaining balance. It consists of three main parts: the external ear, middle ear, and inner ear. Each part plays a crucial role in the process of…
A COMPREHENSIVE GUIDE TO MOTOR PATHWAYS
Introduction Motor pathways are neural pathways that are responsible for controlling voluntary movements in the body. These pathways involve the transmission of signals from the brain to the muscles through a complex network of neurons. There are two main types…
