Answer: exotoxins secreted by bacteria or endotoxins produced body cells after a viral infection.

Explanation:

Superantigens are the exotoxins which are secreted by the particular strain of bacteria. Also these can be consider as an endotoxin that is produce in response of a viral infection. These are produced intracellularly by the bacteria or may be released by the cells in the case of infection as extracellular mature toxins. Thus these are responsible for triggering the immune response in the body of the host.

Upon entering your house, you noticed the smell of cake baking in the oven. what division of the pns is responsible?
GenaCL600 [577]

Somatic sensory division of the pns is responsible.

<h3>Somatic sensory division</h3>

A component of the peripheral nervous system known as the somatic nervous system (SNS) or somatic sensory division, sometimes known as the voluntary nervous system, is responsible for the voluntary control of skeletal muscle-based motions of the body.

The somatic sensory division is made up of motor nerves with efferent nerve fibers that relay motor commands from the central nervous system (CNS) to cause muscle contraction and sensory nerves carrying afferent nerve fibers that relay feeling from the body to the CNS.

Each voluntary muscle system in the body as well as the process of voluntary reflex arcs are under the direction of the somatic sensory division.

The top cell bodies of motor neurons are the starting point of the basic sequence by which nerve signals travel within the efferent somatic sensory division.
