Spinal Cord

To effectively baby proof electrical cords in your home, you can use cord covers, outlet covers, and cord shorteners to keep cords out of reach and prevent potential hazards for your child. Additionally, securing cords with zip ties or cord clips can help keep them organized and out of the way. Regularly inspecting cords for damage and replacing them as needed is also important for safety.

The fluid inside the spinal cord is called cerebrospinal fluid (CSF). CSF is a clear, colorless fluid that surrounds the brain and spinal cord, providing protection and cushioning. It is produced in the brain's ventricles and circulates around the central nervous system, helping to regulate pressure and provide nutrients to the nervous tissue.

Oh, my friend, let's paint a different picture today. It's important to always take care of yourself and seek help if you're feeling overwhelmed. Remember, there are always people who care about you and want to help you through any tough times. Let's focus on creating happy little trees instead.

The brain and spinal cord are both part of the central nervous system. They are involved in processing and transmitting information throughout the body, including sensory input, motor control, and coordination of body functions. Both are protected by the same set of membranes called meninges and surrounded by cerebrospinal fluid.

The major descending motor tract FROM the cerebrum is the corticospinal tract. The major ascending sensory tracts TO the cerebrum are the sensorimotor tract and the dorsal column lemniscal system.

The spinal cord

axons of sensory neurons

Blood vessels are absent from the gray matter of the spinal cord. The gray matter primarily consists of cell bodies, dendrites, and synapses, which are essential for processing and integrating information. Nutrients and oxygen are delivered to the gray matter via the surrounding white matter and cerebrospinal fluid.

Sympathetic nerves originate inside the vertebral column, toward the middle of the spinal cord in the intermediolateral cell column (or lateral horn), beginning at the first thoracic segment of the spinal cord and are thought to extend to the second or third lumbar segments. Because its cells begin in the thoracic and lumbar regions of the spinal cord, the SNS is said to have a thoracolumbar outflow. Axons of these nerves leave the spinal cord through the anterior rootlet/root. They pass near the spinal (sensory) ganglion, where they enter the anterior rami of the spinal nerves. At the synapses within the ganglia, preganglionic neurons release acetylcholine, a neurotransmitter that activates nicotinic acetylcholine receptors on postganglionic neurons. In response to this stimulus postganglionic neurons - with two important exceptions - release norepinephrine, which activates adrenergic receptors on the peripheral target tissues.

The parasympathetic nerves (PSNS) are autonomic (aka "visceral") branches of the peripheral nervous system (PNS). Parasympathetic nerve fibers arise from the central nervous system with the S2, S3, and S4 spinal nerves and from the third, seventh, ninth, and tenth cranial nerves.The parasympathetic nervous system uses chiefly acetylcholine (ACh) as its neurotransmitter, although other peptides (such as cholecystokinin) may act on the PSNS as a neurotransmitter.

remember the word SAME


Sensory are Afferent


Motor are Efferent

Yes, peripheral nerves connect the spinal cord to the limbs and other parts of the body. These nerves carry messages between the brain and the rest of the body, allowing for movement and sensation.

The three outer layers of the grey matter of the cerebellum are the molecular layer, the Purkinje cell layer, and the granular layer. These layers contain different types of cells that play important roles in processing and coordinating motor movements.

Interneurons are the neurons in the center of the spinal cord that receive information from sensory neurons and then communicate this information to the motor neurons. They are responsible for processing and integrating the sensory input before sending signals to the motor neurons for appropriate responses.

Yes, indeed a person can die from this. But than again, it is highly unlikely a person will lose enough CSF to die, it usually patches off and stops draining. Now the CSF can cause pressure in the brain and it can cause death. That's the only way I know of that has to do with csf and dying

So more so, it can lead to death. But it don't necessarily cause death itself.

True. The medulla oblongata regulates vital involuntary functions such as heart rate, blood pressure, and respiration.

pressure is measured in "bar" 1bar is equal to 1000millibar. this is the atmospheres base pressure. 1020millibar is high atmospheric presure. 980 mb is low air pressure. 1.02 or 0.98 bar

The thoracic and sacral curves are the primary curves, as they are obvious at birth. The cervical and lumbar curves are secondary as they are modifications on the foetal position.

Fat cells can potentially be used in spinal cord injury treatment by promoting tissue regeneration and providing a source of stem cells for repair. These cells have the ability to differentiate into various cell types that can contribute to the healing process and support nerve regeneration in the damaged area. Additionally, fat cells can be harvested from a patient's own body, reducing the risk of rejection and facilitating personalized treatment.

The human spinal cord typically weighs about 35-40 grams.

== == I don't know if brain tumors calcify or if the plaque that forms in Alzheimer's Disease involves any type of calcification. Probably the best place to look is a site specifically devoted to Med School and to neurology and brain surgery. [See Comments.]

Yes, ingesting correction fluid can be fatal. It contains toxic chemicals that can cause severe damage to internal organs and lead to potentially deadly complications such as poisoning, organ failure, and respiratory distress. If someone has ingested correction fluid, seek immediate medical attention.

ventral root from the ventral horn of the spinal cord is motor. If ventral root is cut it will lead to to a kind of paralysis called flaccid paralysis. This is because ventral horn contains lower motor neurons. As such the skeletal muscle innervated by the root is paralysed

Glottis

This describes a minor bulging of a spinal disc at the L5-S1 level, which is causing a slight compression of the thecal sac (the membrane surrounding the spinal cord) and minimal displacement of the epidural fat. It may lead to symptoms like low back pain or sciatica. Tracking the condition with a healthcare provider is recommended.
