Study Notes
Neuron Types
- Afferent Neurons: Sensory neurons that transmit nerve impulses from sensory stimuli to the central nervous system (CNS) and brain.
- Efferent Neurons: Motor neurons that carry neural impulses away from the CNS to muscles, facilitating movement.
Sensory Receptors
- Mechanoreceptors: Specialized sensory receptors that detect distortion in body tissues caused by pressure or movement.
Interneurons
- Neurons located within the brain and spinal cord that process information by connecting sensory inputs with motor outputs, playing a crucial role in reflexes and complex behaviors.
Enzyme Kinetics
- Enzyme activities depend on the concentrations of both the enzyme and its substrate.
- Environmental factors such as temperature and pH levels significantly influence enzyme performance.
Km (Michaelis-Menten Constant)
- Represents the substrate concentration at which the reaction velocity is half of the maximum velocity (Vmax).
Germ Layers
- Endoderm: The innermost germ layer responsible for forming the lining of the digestive and respiratory systems.
- Mesoderm: The middle germ layer that develops into muscles, and components of the circulatory, reproductive, and excretory systems.
- Ectoderm: The outermost germ layer that gives rise to skin and nervous tissue.
