Zusammenfassung	This flashcard set delves into the intricate workings of the nervous system, focusing on the brain, spinal cord, and nerves, and their functions. It covers key discoveries by scientists like Galen, Descartes, and others, exploring topics such as the structure and roles of the cerebrum and cerebellum, the distinction between dorsal and ventral roots, and the electrical nature of nerve signals. Ideal for university students studying psychology, this flashcard set provides a comprehensive overview of historical and modern understandings of the nervous system, making it invaluable for those seeking to grasp the complexities of neural functions and their impact on the body.

What is the function of white matter?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

It is continuous with nerves of the body and contains fibers that bring information to and from the grey matter.

How is the nervous system decided?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

It is divided into central devision (brain and spinal cord) and peripheral division (nerves).

What is the 19th century view of the brain?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Injury can disrupt sensation and movement and thought. Brain communicates with body via nerves. Has different parts with different functions. Operates like machine and follow law of nature.

What did Galvani and Bois-Reymond discover about nerves?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Muscles cam be caused to twich when nerves are stimulated electrically and the brain itself can generate electricity. --> Nerves are wires that conduct electrical signals to and from the brain.

What did Bell and Magenkrebs discover?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

Just before nerves attach to spinal cord the fibers devide into 2 branches. Dorsal root: enters toward back of the spinal cord. Ventral root enters toward the front. Cutting ventral roots causes muscle paralysis.

What is the function of Dorsal roots?

Tastatur-Befehle:

= drehen,

= vor-/rückwärts,

= scrollen

They carry sensory information into the spinal cord.
