What are the 3 things that sympathetic preganglionic axon reaches a trunk ganglion?
Sympathetic preganglionic axons reach a trunk ganglion through three key pathways: (1) they may synapse directly with postganglionic neurons in the ganglion, (2) they can ascend or descend within the sympathetic trunk to synapse at a different ganglion, or (3) they may pass through the ganglion without synapsing and continue to target organs via splanchnic nerves. These pathways enable the sympathetic nervous system to coordinate responses throughout the body effectively.
What other body system is directly connected to the sympathetic nervous system?
The sympathetic nervous system is directly connected to the cardiovascular system. Activation of the sympathetic nervous system leads to an increase in heart rate, stronger heart contractions, and constriction of blood vessels, helping to prepare the body for fight or flight responses.
Do endocrine glands secrete hormones directly into the bloodstream?
Yes, endocrine glands secrete hormones directly into the bloodstream.
How does the synaptic nervous system affect the iris?
The iris is not innervated directly, however the iris sphincter muscle is affected by the sympathetic and parasympathetic nervous systems. Sympathetic stimulation causes pupil dilation while parasympathetic nervous system causes pupil constriction. The parasympathetic response is quicker because of the proximity of a parasympathetic ganglion (ciliary ganglion) to the eye. The sympathetic response is slower because all sympathetic ganglia are confined to the spinal cord. This is the reason why people adjust faster to a bright shining light than darkness.

What are ductless organs or group of cells that secrete hormones directly into the bloodstream?
Endocrine glands are ductless organs or groups of cells that secrete hormones directly into the bloodstream. These hormones travel through the bloodstream to target organs and tissues, where they regulate various physiological processes and responses in the body. Examples of endocrine glands include the thyroid, pancreas, and adrenal glands.
Where do endocrine glands secrete hormones in the human body?
