Chapter 1: Peripheral Nervous System Cells

This set of vocabulary flashcards covers biological organization levels, chemical units, and nervous system terminology as discussed in the Chapter 1 lecture transcript.

Micron ($1\,\mu m$)

A scale of measurement equal to one thousandth of a millimeter ($1/1000\,mm$).

Atoms

The smallest stable chemical units in human bodies.

Molecules

The combination of different atoms.

Cells

The fundamental and basic smallest units of life that can self-replicate and perform metabolism (transcribed as capitalism).

Neural Tissues

A major tissue type involving neurons, the central nervous system ($CNS$), or peripheral nervous system ($PNS$) cells.

GI Tract

The digestive system.

Organ System

A level of organization where multiple organs work together to perform specific functions, such as the respiratory or cardiovascular systems.

Organism

The level of organization formed when multiple organ systems come together and work as a whole.

RNA Virus

Microscopic pathogens that exist at a scale typically under one micron ($1\,\mu m$).
