A method of raising livestock and moving herds.
whenever one turns the pages of a book, uses a pen to take notes, or raises one's hand, one's actions are made possible by the somatic nervous system.
The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system that controls skeletal (voluntary) muscles to control body movement. It also connects the organism to its environment by receiving external stimuli through the senses of sight, hearing, taste, and smell. In contrast to the autonomic nervous system, which functions largely independently of conscious control in innervating heart muscle and exocrine and endocrine glands, the somatic nervous system uses efferent motor nerves to govern voluntary actions like walking and smiling.

The Structural Organization of
Cells. The cell is the smallest matter that still absorbs the characteristics
of life. All cells have three basic parts, a plasma membrane splits each cell
from the environment, permits the flow of molecules across the membrane, and
consist receptors that can affect the cell’s activities. A DNA-containing
region occupies a portion of the interior. The cytoplasm contains
membrane-bound compartments (except bacteria), particles, and filaments & end
ash; all bathed in a semifluid substance. Eukaryotic cells are defined by their
possession of a membrane-bound nucleus. Prokaryotic cells have no defined
nucleus; the only representatives are bacteria.
