BRAIN
This organ controls the entire body
What is the brain?
This long part of the neuron carries electrical signals away from the cell body.
What is the axon?
Neurons that
Consists of brain and spinal cordCNS (Central Nervous system)
The most common neurological disorder, characterized by recurrent seizures
Epilepsy
This part of the brain helps you balance and coordinate your movements
What is the cerebullum?
This part of the neurons contains the substance and is responsible for processing incoming signals.
What is a cell body (soma)?
Neurons that carry signals from the CNS to muscles and glands
Motor (efferent) neurons
A stroke occurs when this type of tissue is damaged due to interrupted blood supply.
Brain tissue (neurons)
This part of the brain is responsible for regulating body temperature, hunger, thirst, and basic survival behaviors.
What is the hypothalamus?
This ion rushes into the neuron during depolarization.
What is sodium (Na⁺)?
This part of the PNS controls involuntary activities like heart rate, digestion and breathing
Autonomic nervous system
Degenerative disease that affects memory, thinking, and behaviour, and is the most common cause of dementia
Alzheimer's disease
Damage to this area in the frontal lobe causes difficulty producing speech, while comprehension remains intact.
What is Broca’s area?
This ion plays a key role in the release of neurotransmitters from the presynaptic neuron
What is Calcium (Ca²⁺).
These cells in the CNS support and protect neurons but do not transmit impulses
glial cells or neuroglia
These headaches are often described as a throbbing pain on one side of the head, sometimes with nausea or sensitivity to light.
What are migraines?
This deep brain structure is crucial for forming long-term declarative memories and is one of the first regions affected in Alzheimer’s disease.
What is the hippocampus?
These specialized proteins on the postsynaptic membrane bind neurotransmitters and initiate a cellular response.
What are neurotransmitter receptors?
This structure connects the two hemispheres of the brain, allowing communication between them
Corpus calossum
Autoimmune disorder that attacks myelin sheath in the CNS, leading to symptoms like muscle weakness and impaired coordination.
Multiple sclerosis
