The sympathetic nervous system's stimulation response is balanced by the parasympathetic nervous system's ________ response.

Answers

Answer: akinesia

Explanation:because it’s a nervous system

The sympathetic nervous system stimulation response is balanced by the parasympathetic REST and DIGEST response.

The autonomic nervous system (ANS) is divided into the parasympathetic nervous system and the sympathetic nervous system.

The parasympathetic nervous system is responsible for normal body functioning and homeostasis, whereas the sympathetic nervous system deals with the fight, flight, or freeze responses.

The parasympathetic system promotes rest-and-digest activities when the body is at rest.

In conclusion, the sympathetic nervous system stimulation response is balanced by the parasympathetic REST and DIGEST response.

Which is the BEST statement about joint flexibility? A. It is constant for any joint type. B. It is constant within a family. C. It is consistent between an individual's joints. D. It varies from joint to joint. Please select the best answer from the choices provided. A B C D.

Which is the BEST statement about joint flexibility?

Answer : D

Explanation : It varies from joint to joint.

Hope this helps you!

The amount of flexibility can vary greatly from joint to joint and is affected by various factors such as joint structure, muscle strength and elasticity, age, and physical activity level. Hence option D is correct.

What is joint flexibility?

Joint flexibility refers to the range of motion (ROM) of a joint or a group of joints. It is the ability of a joint to move through its full range of motion without causing any pain or discomfort.

Joint flexibility is an important aspect of physical fitness and is essential for performing daily activities and participating in sports and exercise.

Joint flexibility is determined by several factors, including the anatomy of the joint, the length and elasticity of the muscles surrounding the joint, and the presence of any injuries or medical conditions affecting the joint.

Some joints, such as the shoulder joint, are naturally more flexible than others, like the knee joint.

Flexibility can vary between individuals and between different joints in the same individual. For example, someone may have very flexible hip joints but limited flexibility in their shoulder joints.

Similarly, an individual's joint flexibility can also be influenced by age, gender, and activity level.

Hence option D, It varies from joint to joint. is correct.

compared to parasympathetic ganglia, sympathetic ganglia are __________.

Answers

Compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations, such as: defense or flight reactions to a dangerous situation.

In the parasympathetic ganglia, the axons of neurons are characterized by being very long and reach the very structure of the target organ before making contact with the second neuron.

On the other hand, these ganglia activate the parasympathetic system that has to do with energy recovery situations such as: activating digestive secretions, reducing blood flow to the brain, which causes drowsiness.

In the sympathetic ganglia, axons originate from neurons located in the lateral horns of the spinal cord and exit through the anterior roots of the spinal nerves, along with those of the motor neurons.

These ganglia activate the sympathetic system that prepares the body for dangerous situations causing: increased heart rate, blood pressure, respiratory rate, etc.

Therefore, we can conclude that compared to parasympathetic ganglia, sympathetic ganglia are autonomic ganglia of the sympathetic nervous system that prepare the body for emergency situations.

A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.

Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.

A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.
