The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. The SoNS consists of efferent nerves responsible for stimulating muscle contraction, including all the non-sensory neurons connected with skeletal muscles and skin.
The somatic reflex arc is a neural circuit that travels through the spinal cord. It allows the body to respond to the stimulus before the brain interprets the message/ impulse. For example, when you burn yourself, you automatically pull your hand away without even thinking about it.
When a stimulus causes a message in the sensory receptors, it travels along a sensory neuron, then reaches an interneuron. Here, it SPLITS. One message goes to the brain, but one message goes to a motor neuron. The message in the motor neuron causes the muscle to contract before the brain can even interpret the message.

An efferent somatic (pudendal nerve) output to the external sphincter which relaxes the external sphincter and causes the urine to flow through the urethra is the effector part of the reflex arc.
yes it is somatic
Hormones have nothing to do in reflex arc.
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
The Patellar reflex is an example of a somatic reflex. This refers to the branch of the nervous system that the reflex pertains to. The somatic branch is part of the Peripheral Nervous system, meaning that it's reflex arc does not pass through the central nervous system (the spinal cord and the brain)
it is a somatic reflex

No, a somatic reflex are the reflexes of the skeletal muscle movements. The gag reflex is considered to be an autonomic reflex.
yes it is somatic
yes, the knee relfex felt when tapped just below the knee cap on the patellar tendon is a somatic reflex which is a contraction of skeletal muscles. the opposite would be autonomic relfexes which consist of contractions of smooth or cardiac muscle or secretion by glands.
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
yes
Hormones have nothing to do in reflex arc.
