Neural Communication
Cells that act as information processors and are necessary for all tasks of the nervous system
What are Neurons?
Consists of the brain and the spinal cord
What is the central nervous system (CNS)
chemical substances produces by glands
What are hormones
The largest part of the brain
What is the Forebrain
A machine that uses a magnetic field to allow hydrogens atoms to move around and then emit electromagnetic signals.
What is a MRI
Extensions from the soma that receive incoming signals from other neurons
What are dendrites?
Made of think axons called nerves that carry messaged back and forth between the CNS and the muscles, organs, and senses.
What is the peripheral nervous system
Secretes insulin and glucagon to regulate blood glucose levels
What is the pancreas
Located in the front of the brain and contains the prefrontal cortex, the motor cortex, and Broca's area
What is the Frontal Lobe
Uses a radioactive substance to trace brain activity that creates pictures of the active brain
What is a PET scan
Neurons bind with corresponding __________ on the dendrites of adjacent neurons
What are receptors
Relays sensory and motor information to and from the CNS. Often thought of conscious or voluntary
What is the somatic nervous system
Often called the "master gland" this glands messenger hormones control all the glands in the endocrine system
What is the pituitary gland
Contain the somatosensory cortex which processes sensory information such as touch, temperature, and pain
What is the Parietal Lobe
A machine that uses x-rays to pass through tissues of different densities and rates. Often used to look for tumors
What is a CT scan
chemical messenger of the nervous systems
What are neurotransmitters?
This nervous system helps prepare the body for stress-related activities
What is the sympathetic nervous system
This gland is located in the neck and regulates growth, appetite, and metabolism
What is the Thyroid gland
Located on the side of the head and is associated with memory, emotions, and contains the auditory cortex and Wernicke's area.
What is the Temporal Lobe
A machine that uses a magnetic field to allow hydrogens atoms to move around and then emit electromagnetic signals and shows brain activity over time by tracking blood flow and oxygen levels
What is a fMRI
The storage site for neurotransmitters
What is the synapse vesicle
allows the body access to energy reserves and heightened sensory capacity so that it might fight off a threat or run away safely.
What is the fight and flight response
This gland secretes hormones such as epinephrine and norepinephrine in response to stress
Part of the brain responsible for regulating homeostatic processes such as regulating blood pressure, body temperature, and appitite
What is the Hypothalamus
Uses electrodes that are placed on a person's body to track electrical activity
What is an EEG
