How Neurons Work (1 of 3): Neuron Structure and Resting Potential (BioFlix tutorial)?

1 answer:

6 0

A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.

As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.

The real membrane potential will be between NA+ and K+ of equilibrium potential. However, it will be closer to the equilibrium potential of the ion type with higher permeability.

In the cranial nerve model, which best describes the location of the optic chasma:________

eimsori [14]

Answer:

Cranial Nerves:

The cranial nerves are the set of 12 pairs of nerves which are originated from the brain. As they are responsible for some of the essential functions , such as vision, smell, and balance of the human body structure.

The 12 pairs of the cranial nerves are as as under:

The olfactory nerve
The optic nerve
The oculomotor nerve
The trochlear nerve
The trigeminal nerve
The abducens nerve
The facial nerve
The vestibulocochlear nerve
The glossopharyngeal nerve
The vagus nerve
The spinal accessory
The hypoglossal nerve,

It is very hard for the students to remember all the names of the cranial nerves as we can just recall them by memorizing the device-Old Opie Occasionally Tries Trigonometry And Feels Very Gloomy, Vague And Hypoactive.

Explanation:

Optic chasma:

The optic chasma originates as one of the cranial nerves, as it serves for the function of vision sense in human body. The nerves are responsible for carrying the set of information and data from the retina of the eye to the brain. As the communication between the two regions or part of the body, as they hold the capacity to carry the charges or information from the retina of the eye towards the brain.

Lisa had 20 grams of water. She poured out 15 grams. Which of the following physical properties of the water changes? (4 points)

Black_prince [1.1K]

Answer:

Volume

Explanation:

The boiling point and density of water never changes, no matter how much you add

So the answer CAN'T be Boiling point or Density

Electrical Conductivity changes only when the number of ions in a solution changes

So it CAN'T be Electrical Conductivity

It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture

Which structure in the cheek cell did you observe that separates and protects the cell from the environment?

stellarik [79]

The answer is epithelium. In particular, stratified squamous epithelium. Epithelium is protective tissue that is found on the outer surfaces of organs and blood vessels and inner surfaces of cavities in many internal organs. Epithelium contains no blood vessels, and nutrients reach the epithelial cells through diffusion from the underlying tissue.

World class speed skaters can skate a 3,000-m course in about 4 minutes. What is their average speed for this course.

Semenov [28]

A. 12.5 m/s.

The average speed is defined as the relationship between the displacement made by a body and the total time it took to perform it.

The formula that will allow you to calculate the average speed is:

v = d/t, where d is the traveled distance and t the time it took to travel the distance.

We hace to convert 4 minutes to second:

(60 s/1 min)*(4 min) = 240 s

So, the average speed is:

v = 3000 m/240 s

v = 12.5 m/s
