What are the applications of human nervous cells?
Andreyy89

The human body is made up of trillions of cells. Cells of the nervous system, called nerve cells or neurons, are specialized to carry "messages" through an electrochemical process. The human brain has approximately 86 billion neurons. To learn how neurons carry messages, read about the action potential.

Neurons come in many different shapes and sizes. Some of the smallest neurons have cell bodies that are only 4 microns wide. Some of the biggest neurons have cell bodies that are 100 microns wide. (Remember that 1 micron is equal to one thousandth of a millimeter!).

Neurons are similar to other cells in the body because:

Neurons are surrounded by a cell membrane.

Neurons have a nucleus that contains genes.

Neurons contain cytoplasm, mitochondria and other organelles.

Neurons carry out basic cellular processes such as protein synthesis and energy production.

However, neurons differ from other cells in the body because:

Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body.

Neurons communicate with each other through an electrochemical process.

Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).

The Neuron

neuron

One way to classify neurons is by the number of extensions that extend from the neuron's cell body (soma).

bipolar neuron

Bipolar neurons have two processes extending from the cell body (examples: retinal cells, olfactory epithelium cells).

Pseudounipolar cells (example: dorsal root ganglion cells). Actually, these cells have 2 axons rather than an axon and dendrite. One axon extends centrally toward the spinal cord, the other axon extends toward the skin or muscle.

Multipolar neurons have many processes that extend from the cell body. However, each neuron has only one axon (examples: spinal motor neurons, pyramidal neurons, Purkinje cells).

Neurons can also be classified by the direction that they send information.

Sensory (or afferent) neurons: send information from sensory receptors (e.g., in skin, eyes, nose, tongue, ears) TOWARD the central nervous system.

Motor (or efferent) neurons: send information AWAY from the central nervous system to muscles or glands.

Interneurons: send information between sensory neurons and motor neurons. Most interneurons are located in the central nervous system.

Check out the Gallery of Neurons to see some pictures of real neurons or "Sidewalk Cells" to see photographs of neurons on the street.

What is a golgi apparatus and what does it do?
artcher [175]
The Golgi apparatus is responsible for packing proteins from the rough endoplasmic reticulum into membrane-bound vesicles which then trans locate to the cell membrane. At the cell membrane, the vesicles can fuse with the larger lipid bi layer, causing the vesicle contents to either become part of the cell membrane or be released to the outside.

Which of the following is true regarding the structure indicated by the arrow in the joint depicted in A? a. It is composed of h
kari74 [83]

Answer:

Considering A is a picture of a fibrous joint, a suture on the skull, the true answer is c. It becomes ossified late in adult development

Explanation:

Fibrous joints are connected by dense connective tissue, consisting mainly of collagen. A suture is a type of fibrous joint that is only found in the skull (cranial suture). This specific type becomes ossified late in adult development and it is called craniosynostosis, when the fusion is before birth.  These joints are synarthroses.

Which atrial dysrhythmia has a cardiac complex that occurs too soon and may have abnormal p waves, but other than being ''early,
Tatiana [17]

Premature atrial complexes (PAC) dysrhythmia has a cardiac complex that occurs too soon and may have abnormal p waves, but other than being ''early,'' has no other abnormal features.

<h3>What is Cardiology?</h3>
  • Cardiology is a field of medicine that deals with problems with the heart and cardiovascular system.
  • The term "cardiology" comes from the Ancient Greek words "kardi" (heart) and "-logia" (study).
  • Heart failure, valvular heart disease, congenital heart defects, coronary artery disease, and electrophysiology are all covered in the field's spectrum of medical diagnosis and treatment.
  • Cardiologists are among the professionals in internal medicine who work in this area.
  • Pediatricians that specialize in cardiology are known as pediatric cardiologists.
<h3>Why does cardiac happen?</h3>
  • Nearly all heart conditions that are known to exist can result in cardiac arrest.
  • The electrical system of a damaged heart malfunctions most frequently during cardiac arrests.
  • An aberrant heart rhythm like ventricular tachycardia or ventricular fibrillation is brought on by this defect.
