Nervous Flashcards
What does the frontal lobe control?
Thinking, reasoning, planning, and voluntary muscle movements
What does the parietal lobe control?
processes sensory information (touch, temperature, pain) and helps with spatial awareness
What does the temporal lobe control?
Processes sensory information (touch, temperature, pain) and helps with spatial awareness.
What does the temporal lobe control?
The temporal lobe is involved in hearing, memory, and language comprehension.
What does the occipital lobe control?
The occipital lobe processes visual information
What is the dura mater?
The dura mater is the outermost layer of the meninges, providing protection and support for the brain and spinal cord.
What is the arachnoid mater?
The arachnoid mater is the middle layer of the meninges, filled with cerebrospinal fluid (CSF) to cushion the brain
What is the pia mater?
The pia mater is the innermost layer of the meninges, closely adhering to the brain and spinal cord, and carrying blood vessels
What is the function of the cell body of a neuron?
The cell body contains the nucleus and is responsible for maintaining the neuron’s function.
What do dendrites do in a neuron?
Dendrites receive signals from other neurons and transmit them to the cell body.
What does the axon do in a neuron?
The axon transmits electrical signals away from the cell body to other neurons or muscles
What is the function of the myelin sheath?
The myelin sheath insulates the axon, speeding up the transmission of nerve impulses.
What is a hemorrhagic stroke?
A hemorrhagic stroke occurs when a blood vessel in the brain bursts, leading to bleeding in or around the brain.
What is an aneurysm in the context of stroke?
An aneurysm is a bulging blood vessel in the brain that can rupture, causing a hemorrhagic stroke.
What is a thrombotic stroke?
A thrombotic stroke occurs when a blood clot (thrombus) blocks a blood vessel in the brain, preventing normal blood flow.
