Nerve cells (neurons) form the structural and functional units of the central and peripheral nervous systems. Their function is to receive stimuli and transmit nerve impulses to the target organ. Nerve cells consist of a cell body (soma), dendrites, an axon and a specialized cytoskeleton. Dendrites receive and integrate signals from other neurons or from sensory stimuli and their number can vary. However, each neuron only has one axon that transmits the electrical impulses. To increase conduction velocity, axons are insulated with myelin sheaths. In the central nervous system, this function is performed by oligodendrocytes and in the peripheral nervous system by Schwann cells, respectively.

The importance of myelin ⬇️ A myelinated neuron is a type of nerve cell whose axon is wrapped in a fatty, insulating layer called the myelin sheath. - Myelin is a multilayered membrane made of lipids and proteins. - It wraps around the axon (the long, signal-transmitting part of a neuron) like insulation around a wire. * Function of Myelination - Speeds up signal transmission: Myelin allows electrical impulses (action potentials) to jump between gaps in the sheath called nodes of Ranvier, a process known as saltatory conduction. - Energy efficiency: Myelinated neurons use less energy to transmit signals compared to unmyelinated ones. - Protection: The sheath also protects the axon from damage. - Accuracy of information * Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system—specifically the brain and spinal cord. Here's a clear breakdown: - The immune system mistakenly attacks the myelin sheath, the protective covering around nerve fibers. - This leads to inflammation and scarring (sclerosis), disrupting communication between the brain and the rest of the body. #multiplesclerosis #neuron #myelination #neuronaxon #neurologia #biologystudent

The unique structure of neurons permits it to receive and carry messages to other neurons and throughout the body. The neuron contains the soma (cell body), which extends the axon (a nerve fiber conducting electrical impulses away from the soma), and dendrites (tree-like structures that receive signals from other neurons). The myelin sheath is an insulating layer that forms around the axon and allows nerve impulses to transmit more rapidly along the axon. #neuron

The vestibulocochlear nerve, also known as cranial nerve VIII, is responsible for transmitting sensory information related to: Functions 1. Hearing: The cochlear division transmits sound information from the cochlea to the brain. 2. Balance and equilibrium: The vestibular division transmits information about head position, movement, and acceleration. Components 1. Cochlear nerve: Responsible for hearing. 2. Vestibular nerve: Responsible for balance and equilibrium. Clinical Significance 1. Hearing loss: Damage to the cochlear nerve can cause hearing loss or tinnitus. 2.Vertigo and dizziness: Damage to the vestibular nerve can cause vertigo, dizziness, and imbalance. Assessment 1. Hearing tests: Audiometry and other hearing tests can assess cochlear function. 2. Vestibular function tests: Electronystagmography (ENG), videonystagmography (VNG), and rotational chair testing can evaluate vestibular function. Related Conditions 1. Sensorineural hearing loss: Damage to the cochlear nerve or inner ear can cause permanent hearing loss. 2. Vestibular disorders: Conditions like benign paroxysmal positional vertigo (BPPV), labyrinthitis, and vestibular neuritis can affect the vestibular nerve. #vestibular #hearingloss #vestibularcochlearnerve #physiotherapy #trendingreelsvideo #vertigo #trendingreels #audiometery #sensorineuralhearingloss #vestibulardisorder #bppv #balance

🧠 Structure of Neuron 🧠 Neurons are the basic structural and functional units of the nervous system. They transmit signals between different parts of the body and the brain. Key Parts of a Neuron: 🔹 Dendrite – Receives signals 🔹 Nucleus – Controls cell activities 🔹 Cell Body (Soma) – Maintains cell function 🔹 Axon Hillock – Initiates nerve impulse 🔹 Myelin Sheath – Speeds up signal transmission 🔹 Node of Ranvier – Helps in conduction of impulses 🔹 Schwann Cell – Produces myelin 🔹 Axon Terminal – Passes signals to next cell ✨ Neurons = Communication highway of the human body! #Neuron #NeuroScience #BrainFacts #HumanAnatomy #NervousSystem

An action potential is an electrical signal that travels along a nerve cell. It begins when a neuron gets a strong enough stimulus to open ion channels in its membrane. Sodium ions (Na⁺) rush in, making the inside of the neuron more positive. This change moves down the axon like a wave, carrying the signal quickly. Then potassium ions (K⁺) flow out to reset the charge so the neuron can fire again. It’s how your brain sends messages to your body! ⚡🧠➡️ #nervesignal #brainpower #actionpotential #howwemove #biology #biologia #biologie #interesting #sportsmedicine #studyinspiration #aestheticmedicine #scienceexplained #medicalscience #sciencememes #AmazingBody #Science #healthfirst #naturemagic #BodyFacts #sciencefacts #stayhealthy #austria🇦🇹 Source | https://www.youtube.com/watch?v=oa6rvUJlg7o&t=1s THANK YOU: Harvard Extension School
