Bundles of axons in the central nervous system are called

Biology
1 answer:
Karolina [17]3 years ago
7 0

Answer: Bundles of axons in the central nervous system are called a "tract"

Explanation:

Axons(nerve fiber) consist of long slender projection of neurons or nerve cells that conduct and transmit impulses away from the neuron or nerve cell body. Axons are surrounded by endoneurium layer which contain protein fluid that surround each axon.

Bundles of axon in the CNS is known as tract. We have ascending tracts and descending tracts. The ascending tracts function are to conduct and carry impulses along the spinal cord to the brain while the descending tracts transmit and carry the impulses from the brain to lower regions (downward) of the body. Tracts are identified by their origin (where the bundle start) and also the end/termination of axon bundle.

The largest tracts are fasciculi gracilis and cuneatus which are known as ascending tracts.

grin007 [14]

Answer:

Structure of large intestine: Large intestine is the part of digestive system which comes in the end. It consist of four parts. Large intestine length is 150 cm and width is 5 cm.

Function of large intestine: It performs two main functions.

1) Large intestine helps in the absorption of water and nutrients from the food which cannot be digested in the stomach.

2) It removes the waste material from the body in the form of feces.

How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
Novay_Z [31]

Explanation:

<u>Three.</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
  • This happens in the thykaloids, where pigment molecules reside like chlorophyll.
  • Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.

Which factor does not play a role in runoff
vladimir1956 [14]
<span>Infiltration is the process by which rainwater becomes groundwater. In the water cycle, which involves primarily; evaporation, condensation and precipitation. Henceforth, after precipitation comes infiltration in the land areas leaving the rainwater aggregated in a single location which accumulates over time. Then this process is followed by runoff and subsurface flow by which water flows through other bodies of water, either in river, sea or ocean, even lake. Other rainwaters that has segregated and wasn’t able to transport itself stays in the process of infiltration, thus groundwater.<span>

Thus, solar radiation doesn't play a role in runoff or infiltration.

How would an x-ray technician position the camera to produce a frontal view of a patient's abdominal cavity?
leva [86]

Answer: Option A. "In front of the patient, pointing at his navel"

Explanation:

The X-ray of abdominal cavity is known as Abdominal x-ray. It has same principle as X-ray and uses ionizing radiation to take pictures of inner parts of abdominal cavity such as intestine, stomach, liver and spleen. it is used to diagnose patients with vomiting, unexplained pain, and nausea.

While diagnosing  patient's abdominal cavity, x-ray technician position the camera in front of the patient, pointing at his navel in order to produce a frontal view of abdominal cavity.

Talking about a x-ray machine, it is a compact apparatus which can be taken to the patient in a hospital bed or the emergency room. The x-ray tube connects flexible arm which further extends towards the patient and an x-ray film holder (image recording) plate is placed under the patient.

The technologist will ask the patient to take position on the x-ray table or bed and will position x-ray machine over the abdominal area of the patient, in order to take the frontal view of abdominal cavity. The patient will be asked to hold their breathe to get a clear picture. The technician will turn on the x-ray machine that allows  x-ray machine  to produce a small burst of radiation which passes through the abdominal area and records the frontal view of  patient's abdominal cavity. As a result, soft tissue shows up in shades of gray and air appears black while bones appear white on the x-ray, through which patient can be diagnosed.

Hence, the correct option is A "In front of the patient, pointing at his navel".
