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.
