Answer:
<u>d. Skeletal muscle</u>
Explanation:
There are two components of efferent nervous system.
- <u>Somatic nervous system</u>
- <u>Autonomic nervous system</u>
<u>SOMATIC NERVOUS SYSTEM:</u>
Somatic nervous is one of the components of efferent/motor nervous system.
It controls <u>voluntary activities</u>. It involves the <u>control of skeletal muscles</u>.
It is composed of <u>the motor neuron and the innervating muscle</u>.
<u>AUTONOMIC NERVOUS SYSTEM:</u>
Autonomic nervous system is the other efferent/motor system of the body. It controls the <u>involuntary activities</u>. It involves the control of <u>cardiac muscle, glands and smooth muscles</u> of the body.
It is composed of<u> 2 neurons; preganglionic and postganglionic neurons.</u>
Autonomic nervous system is further divided into:
- Sympathetic nervous system (it is responsible for flight and fight responses)
- Parasympathetic Nervous system (it is responsible for rest and digestion)
- Enteric division ( controls Gastrointestinal system)
<u>QUESTION:</u>
<u>d. skeletal muscle</u>
This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.
The term "submandibular lymphadenopathy" describes swollen lymph nodes under the mandible (lower jaw). Infection is typically indicated by hot, swollen, sensitive, and pliable lymph nodes that are also accompanied by other symptoms.
Additionally, infections of the upper respiratory tract, tonsils, sinuses, or from mononucleosis and cut-scratch disease can cause submandibular lymphadenopathy.
<h3>What is lymph node ?</h3>
A small bean-shaped element of the immunological system. White blood cells called lymphocytes, which are found in the lymph nodes of the body, help the body fight off disease and infection. They remove materials that the lymphatic fluid does not filter. There are thousands of lymph nodes all across the body.
- Immune cells are produced in lymph nodes to help in the fight against infection. They also filter the lymph fluid to remove contaminants like pathogens and cancerous cells. They can swell as a result of swelling, an abscess, cancer, and—most commonly—inflammation.

The correct answer is Economic cycle.
The natural fluctuation in economy between the period expansion (economy growth) and contraction (recession) is known as the economic cycle.
The normal growth and downturn in the economy is the basic definition of Economic cycle.
During the time of expansion the investors seek to purchase companies and shares and during the time of contraction the investors look to invest and purchase the companies such as utilities and healthcare.
The complete statement is this: Information that sensed in the right visual field is processed in the LEFT HEMISPHERE OF THE BRAIN.
The eye is an organ of sight that is used to receive physical stimuli in the form of light. The light is then sent as electrical stimuli to the brain for interpretation.
The eyes are constructed in such a way that, the left hemisphere of the brain process visual information from the right eye while the right hemisphere of the brain process information from the left eye. The optic chiasm, which is a complicated crossover of optic nerves fibers located behind the eyes at the bottom of the brain makes this to be possible.
Explanation:
Sound travels in the form of a wave. Waves are characterized by three basic quantities. They are frequency, speed, and amplitude. Two of the main characteristics of sound are pitch and loudness, which in turn are determined by the frequency and amplitude of the wave, respectively.
