Which of the following describes a system?

Identify, define and break down 10 medical terms related to the nervous system.

lutik1710 [3]

Axons are long nerve processes which carry nerve impulses from the Soma to other neurons, they vary in length but can become almost as long as half of the human body.

The soma (body) of the neuron contains the nucleus which acts as the cell's control centre, these contain many small neurofibrils which project from the nucleus into the dendrites.

Dendrites are short, thick processes which branch out of the soma in a tree like manor. They conduct nerve impulses to the soma.
The three categories of neurons:

Afferent (Sensory) Neurons have the dendrites connected to receptors such as the eyes, ears etc. These receptors change the information they receive into electrical impulses that are transmitted to other neurons. In sensory neurons the axons are connected to other neurons.

Efferent (Motor) Neurons have the dendrites connected to other neurons, the axons are connected to effectors. Effectors are either glands or a muscle cell that is the receiving end of the nerve impulse. The nerve, when excited will cause the effector to react (move, contract, or secrete etc).

Internuncial Neurons have both the dendrites and the axons are connected to other neurons. They are sometimes referred to as connector neurons.
Internuncial neurons are found throughout the body, but especially in the spinal cord and brain.

Properties and characteristics of Neurons:
Normally the electrical impulses (messages) travel through a neuron in only one direction.

The axon may be surrounded by a 'coat' of lipids (fats) and proteins known as the myelin sheath which acts as an insulator.

Neurons are specialist cells that have lost the ability to reproduce themselves. Once the soma of a neuron has died the entire neuron dies, and can never be replaced.
Repair of damaged neurons only occurs in myelinated neurons.

white matter are coloured by myelin, consisting of many neurons supported by neuroglia.
grey matter is soma and dendrites or bundles of unmyelinated axons and neuralgia.

Women between the ages of 19 and 30 need 2 cups of fruit on a daily basis and 1 1/2 cups a day after age 30. Adult men should aim to eat 2 cups of fruit each day no matter their age. You might need to consume more fruit even if you are very active and eat a higher-calorie diet, according to ChooseMyPlate.gov, a website from the United States Department of Agriculture.</span>

BEST ANSWER GET BRAINLIEST Describe in 2-3 sentences which of the elements of effective communication (speaking skills, listenin

DiKsa [7]

Answer:

Effective communication requires a combination of skills including:

Stress management (in the moment)

Appropriate nonverbal communication/Body language

Engaged listening

The capacity to effectively communicate with self-confidence

The ability to identify and understand the emotions of all individuals involved in the communication (including your own)

Nonverbal communication needs to reinforce–not contradict–what is being discussed. When you say one thing and your body portrays another, listeners may feel as if you are not being truthful. For instance, if you begin discussing how happy you are with a staff member’s ability to take a month off and travel the world, but your hands are folded in front of you and you avoid making eye contact, you are speaking one thing and your body is saying the opposite.

Communication requires engaged listening; therefore, planning your next sentence, checking emails and text messages or just thinking about what you want for lunch interferes with your ability to focus. Staying focused from one moment to the next ensures that you do not miss any of the nonverbal cues used during the conversation.

Solutions:

During discussions, concentrate on the here and now.

Let the speaker know you are listening with small gestures like nodding your head or short verbal responses.

Listen for the subtle changes in the speaker’s voice, pay attention to his or her body language and other nonverbal clues. These actions tell you how the person feels and what they are trying to communicate to you.

Whenever you find it difficult to concentrate on a conversation, repeat the words in your head. This will reinforce their message and make it easier for you to remain focused.

Do not interrupt or attempt to redirect the conversation to address your concerns.

Favoring your right ear can help you pick up on the subtle emotional nuances an individual is portraying. This tip works because the right ear is connected to the left side of the brain, which contains the main processing centers for emotions and speech comprehension. Try standing (or sitting) straight with your chin down while tilting your right ear towards the individual speaking.
