⩥ Sensory neurons. Answer: Transmit sensory information from sensory
receptors to the brain and spinal cord.
⩥ Motor neurons. Answer: Carry commands from the brain and spinal
cord to muscles and glands.
⩥ Interneurons. Answer: Communicate between sensory and motor
neurons within the brain and spinal cord.
⩥ Glial Cells. Answer: Support neurons by providing structural support,
nutrients, insulation, and waste removal.
⩥ Astrocytes. Answer: Provide support and nutrition to neurons,
maintain the blood-brain barrier.
⩥ Oligodendrocytes. Answer: Form myelin in the central nervous
system (CNS).
,⩥ Schwann cells. Answer: Form myelin in the peripheral nervous
system (PNS).
⩥ Microglia. Answer: Act as the immune system of the brain, cleaning
up dead neurons and pathogens.
⩥ Central Nervous System (CNS). Answer: Includes the brain and spinal
cord; processes sensory information and coordinates body functions.
⩥ Peripheral Nervous System (PNS). Answer: Composed of sensory and
motor neurons outside the CNS.
⩥ Somatic nervous system. Answer: Controls voluntary movements of
skeletal muscles.
⩥ Autonomic nervous system. Answer: Controls involuntary functions
(heart rate, digestion) and is divided into sympathetic and
parasympathetic systems.
⩥ Lesion studies. Answer: Involves damaging specific areas of the brain
to observe changes in behavior.
, ⩥ Electroencephalogram (EEG). Answer: Measures electrical activity in
the brain by placing electrodes on the scalp.
⩥ Functional MRI (fMRI). Answer: Measures brain activity by detecting
blood flow changes, indicating areas of the brain that are active during
specific tasks.
⩥ Positron Emission Tomography (PET). Answer: Uses radioactive
substances to visualize active areas of the brain.
⩥ Single-cell recordings. Answer: Measures the electrical activity of a
single neuron to study brain function in greater detail.
⩥ Cell body (soma). Answer: Contains the nucleus and organelles of a
neuron.
⩥ Dendrites. Answer: Receive signals from other neurons.
⩥ Axon. Answer: Transmits electrical impulses away from the cell body.
⩥ Myelin sheath. Answer: Insulates the axon, speeding up signal
transmission.
