Q

controls and regulates temperature, appetite, water balance, sleep, and blood vessel constriction and dilation

A

Hypothalamus

22
Q

also plays a role in the emotions such as anger, fear, pleasure, pain, and affection

A

Hypothalamus

23
Q

located below cerebrum

24
Q

responsible for eye and auditory reflexes

25
located below midbrain (In Brainstem)
Pons
26
responsible for certain reflex actions (such as chewing, tasting, and saliva production)
Pons
27
located at the bottom of the brainstem
Medulla Oblongata
28
connects to the spinal cord
Medulla Oblongata
29
Medulla Oblongata regulates:
- heart and blood vessel - digestion - respiration - swallowing - coughing - sneezing - blood pressure
30
It is also known as "The Center for respiration"
Medulla Oblongata
31
is the link between the brain and the nerves in the rest of the body
The Spinal Cord
32
4 Regions of the Spinal Cord
- Cervical - Thoracic - Lumbar - Spinal Nerves (Afferent and Efferent)
33
carries information from the body to the brain
Afferent Spinal Nerves
34
carries information from the brain to the body
Efferent Spinal Nerves
35
regulates the functions of the Central Nervous System
The Peripheral Nervous System
36
Smaller Systems of the Peripheral Nervous System
1. Somatic Nervous System 2. Autonomic Nervous System
37
is responsible for carrying motor and sensory information
Somatic Nervous System
38
it is made up of nerves that connect to skin, sensory organs, and skeletal muscles
Somatic Nervous System
39
is responsible for nearly all voluntary muscle movements
Somatic Nervous System
40
processes sensory information from external stimuli. (Hearing, Touch, and Sight)
Somatic Nervous System
41
allow communication to happen between the nerves throughout the body in the Central Nervous System
Afferent Sensory Neurons and Efferent Motor Neurons
42
conducting inward
Afferent Sensory Neurons
43
take information from the nerves to the Central Nervous System
Afferent Neurons
44
conducting outward
Efferent Motor Neurons
45
take information from the Central Nervous System to the muscle fibers throughout the body
Efferent Neurons
46
2 Parts of Autonomic
- Sympathetic Nervous System - Parasympathetic Nervous System
47
vital to our survival
Sympathetic Nervous System
48
"Fight or Flight" revs up the body to either defend yourself or escape the threat
Sympathetic Nervous System
49
is the counterbalance to the sympathetic response to danger whether real or imagined
Parasympathetic Nervous System
50
once the threat is gone, it brings all systems of the body back to normal
Parasympathetic Nervous System
