The Nervous System Flashcards
It is the body’s major communication and control network in the form of electrical signals, and relayed constantly from the sense organs to and from the brain, through complex networks of neurons on a timescale measured in milliseconds
Nervous system
It consists of the brain and spinal cord. It is the coordinating system for the body.
Schematic
integration center of communication
Thalamus
directs Pituitary gland
Hypothalamus
master gland, metabolism, growth
Pituitary gland
movement
Basal Ganglia
learning, memory
limbic system
higher order processing of information
Cerebrum
hearing, vision
Tectum
heartbeat, circulation and respiration
Medulla
movement production, motivation
Tegmentum
relay station
Pons
movement, balance and coordination
Cerebellum
a long cylinder of nerve tissue that
extends like a tail from the medulla; serves as the pathway
of information
Spinal cord
It consists of peripheral nerves ang ganglia (spinal, cranial, visceral nerves), the between brain and body.
Peripheral nervous system
It controls voluntary movement
Somatic PNS
It controls involuntary movement
Autonomic PNS
controls for ‘fight or flight’ responses
Sympathetic system
controls for ‘rest and digest’ responses
Parasympathetic system
most smallest neurons
granular cells
begins programming a movement for Motor cortex to execute movement
premotor cortex
4 lobes of the cerebral cortex
Frontal lobe
Parietal lobe
Occipital lobe
Temporal lobe
They are the hill/clefts.
Sulci
They are the ridges/valleys formed along the sulci
Gyri
The large sulcus
Fissure
Its main target is for visual information.
Occipital lobe
It monitors all the information about eye, head, and body positions and passes it on to brain areas that control movement, spatial information and numerical information.
Parietal lobe
the primary cortical target for auditory information.
Temporal lobe
the “control panel” of our personality and our ability to communicate.
Frontal lobe
It is found in the occipital, temporal, and parietal lobes. It processes incoming information from the sensory systems.
Sensory cortex
The association cortex are areas located primarily in the frontal, temporal, and inferior parietal lobes.
Association Cortex
This method allows us to see in detail the size and shape of neurons and their components
Neuroanatomical Techniques
this method uses electrons instead of light to magnify the image to allows us to see features as small as a single molecule of neurochemical.
Electron microscopy
This method allow us to trace the extent of features of the nervous system.
Chemical Staining
It is an imaging technology in which
computers are used to enhance X-ray images to visualize the brain and other internal structures of the living body.
Computerized Axial Tomography (CAT/CT)
It is an imaging technique that provides a high- resolution image of activity in a living brain by recording the emission of radioactivity from injected chemicals.
Positron Emission Tomography (PET).
It is an imaging technique that provides very high-resolution structural images.
Magnetic Resonance Imaging (MRI).
It is a set of tests that tend to be performed poorly by brain-damaged patients in relation to other patients or healthy controls; the scores on each test are added together to form a single aggregate score.
