|
Meyelencephalon |
1. Medulla Oblongata |
|
|
Axon Terminal |
Passes information to next neuron. Communicates with muscles of all types |
|
|
Cell Body |
Processes incoming information Sends signals to cause muscles to contract Synthesizes the neurotransmitters |
|
|
Dendrites |
Ends are called receptors Convert sensation to electric signaleuroglial CN |
|
|
Neuroglial Cells in CNS |
1. Astrocytes 2. Oligodendrocytes 3. Microglia 4. Ependymal Cells |
|
|
Astrocyte |
Forms the blood brain barrier Acts as "scar tissue" in CNS |
|
|
Oligodendrocyte |
Responsible for myelination in the CNS (schwann cells are used in the PNS) |
|
|
Microglia |
Does phagocytosis in CNS. Looks similar to astrocytes |
|
|
Ependymal |
Lines CNS filled ventricles |
|
|
Pseudounipolar Neuron One pole that has split into two branches One branch goes to periphery and the other goes to the spinal cord. |
|
|
Bipolar neuron Has two poles--> one is a dendrite the other is an axon |
|
|
Comprise most of our cells Has a number of dendrites but only 1 axon Can communicate with many other neurons |
|
|
Neurons involved in Reflex Arc |
1. Motor neurons 2. Interneurons 3. Sensory Neurons |
|
|
White Matter composition |
Axons and Dendrites |
|
|
Grey Matter composition |
Cell bodies |
|
|
CNS composition |
Brain Spinal Cord |
|
|
Sulci |
furrow/depression in the brain (valley) |
|
|
Gyri |
Ridge of the cerebral cortex |
|
|
Meningial Layers |
1. Dura Matter 2. Arachnoid Matter 3. Pia Matter |
|
|
Dura Matter |
1. Has a periosteal layer which is usually attached to bone that is separated by a slender gap containing tissue fluids and blood vessels 2. Has a meningial layer--> this is usually attached to the arachnoid |
|
|
Arachnoid matter |
Has a subarachnoid space--> this is filled with CSF (made by ependymal cells) |
|
|
Pia Matter |
The most delicate layer Protects CNS by containing cerebrospinal fluid |
|
|
Ganglia |
Cell bodies outside of the CNS |
|
|
Basal Ganglia |
ganglia at the base of the brain Responsible for control of PLANNING Programming and execution of movements |
|
|
Frontal Lobe |
Responsible for voluntary movement |
|
|
Thalamus |
processes all incoming sensory information All senses go to spinal cord then medulla, pons, midbrain then thalamus Sensory info is then directed to appropriate places Associates sensations with emotions |
|
|
Hypothalamus |
Deep in the cerebrum Regulation of hormone release and sex function Balance; Sleep |
|
|
Pons |
(Hindbrain) Regulation of cardiovascular function, heart rate and bp Means that neurons control respiration Damage to pons=arrested breathing |
