Study Notes
Nervous System
- Sensory neurons carry sensory information from the peripheral nervous system to the central nervous system.
- Motor neurons carry signals from the central nervous system to the peripheral tissues, such as muscles and glands.
Electrical Signals
- Depolarization is the process of reversing the electrical charge across a cell membrane.
- Repolarization is the process of restoring the electrical charge across a cell membrane to its resting state.
- The electrical charge difference between the inside and outside of a cell membrane when the cell is at rest is called the resting potential.
Neuron Structure
- Dendrites receive signals from other neurons or sensory receptors.
- Myelin is a fatty substance that forms a protective sheath around certain nerve fibers, allowing for faster transmission of electrical signals.
Sense Organs
- The vestibular sense is responsible for detecting changes in head position and linear acceleration.
- Otoliths are tiny calcium carbonate crystals in the inner ear that are involved in detecting changes in head position and linear acceleration.
- The sense of taste is also known as gustation.
- The sense of smell is also known as olfaction.
- The sense of balance while moving is also known as equilibrium.
Eye
- The clear, watery fluid that fills the anterior and posterior chambers of the eye is called aqueous humor.
- The process by which the eye adjusts its focus to see objects at varying distances is called accommodation.
- The bending of light as it passes through different media or lenses is called refraction.
Meninges and CSF
- The order of meninges from deep to most superficial is: pia mater, arachnoid mater, and dura mater.
- The primary function of cerebrospinal fluid (CSF) is to cushion and protect the brain and spinal cord.
