These SPINAL nerves carries information from the brain to the body

Answer 23

Efferent Spinal Nerves

Question 24

The subdivisions of Peripheral Nervous System

Answer 24

Somatic and Autonomic

Question 25

Subdivision of Peripheral Nervous System that is responsible for carrying motor and sensory information. It is made up of nerves that connect to skin, sensory organs, and skeletal muscles.

Answer 25

Somatic Nervous System

Question 26

It is a subdivision of the Peripheral Nervous System that is responsible for nearly all voluntary muscle movements as well as the processing of sensory information from external stimuli (Hearing, Touch, etc.)

Answer 26

Somatic NS

Conducting Inward

Answer 27

Afferent Sensory Neurons

Question 28

Conducting Outward

Answer 28

Efferent Motor Neurons

Question 29

These neurons take information from the nerves to the Central NS.

Answer 29

Afferent Sensory Neurons

Question 30

These neurons take information from the Central NS to the muscle fibers throughout the body.

Answer 30

Efferent Motor Neurons

Question 31

2 Subdivisions of Autonomic Nervous System

Answer 31

Sympathetic and Parasympathetic

Question 32

Subdivision of Autonomic NS that is vital for our survival. It revs up the body to either defend yourself or escape a threat. The fight or flight response. Responsible for the acceleration of heart rate, the constriction of blood vessels and the rise of blood pressure.

Answer 32

Sympathetic NS

Question 33

Subdivision of Autonomic NS that brings all systems of the body back to normal after Fight or Flight response. It slows down the heart rate and increases the intestinal and gland activities.

Answer 33

Parasympathetic

Question 34

Type of neuron that is located in the Central Nervous System, it analyzes and interprets the data or impulses.

Answer 37

Limbic System

Question 38

is a change in the environment with sufficient strength to initiate a response.

Answer 38

Stimulus

Question 39

receive stimulus and carries it impulses toward the cell body

Answer 39
