What else can I help you with?
What endocrine glands secrete norepinephrine?
None, nerve endings aren't endocrine glands, are they?
What fibers are the sweat glands innervated by?
Sweat glands are innervated by adrenergic sympathetic nerve fibers from the autonomic nervous system. These fibers release norepinephrine, which stimulates the sweat glands to produce sweat.
What hormones are released from nerve cells rather than endocrine glands?
antidiuretic hormone and oxytocin
Are efferent nerve fibers described as motor nerve fibers?
Yes, efferent nerve fibers are often described as motor nerve fibers. Efferent nerves carry signals away from the central nervous system to muscles and glands, controlling movement and bodily functions.
The regulatory system of humans includes endocrine glands and?
The regulatory system of humans includes endocrine glands and hormones. The endocrine glands release hormones into the bloodstream to regulate various body functions such as growth, metabolism, and reproduction. These hormones act as chemical messengers and help maintain balance within the body.
Where is the part where the postganglionic fiber and the spinal nerve innervate glands in the body?
Postganglionic fibers innervate glands in the body primarily through the autonomic nervous system, specifically the sympathetic and parasympathetic divisions. These fibers originate from autonomic ganglia and connect to target tissues, including glands, often by traveling alongside spinal nerves. In the case of sympathetic innervation, postganglionic fibers may follow blood vessels or directly innervate glands like the adrenal medulla. In contrast, parasympathetic fibers arise from cranial nerves and sacral spinal nerves, directly influencing glands such as salivary and lacrimal glands.
Are neurons in the endocrine system?
No, neurons are not part of the endocrine system. Neurons are nerve cells that transmit signals through electrical impulses, while the endocrine system consists of glands that secrete hormones into the bloodstream to regulate various bodily functions.
Nerve fibers scattered throughout the dermis are associated with what?
Nerve fibers scattered throughout the dermis are associated with sensing touch, pressure, temperature, and pain. These nerve fibers help to relay sensory information to the brain for processing and response.
What is a neuroglandular junction?
A neuroglandular junction is the site where nerve fibers stimulate the release of hormones from endocrine glands. Nerve impulses trigger the release of neurotransmitters that can stimulate or inhibit hormone production and release. This communication pathway is important for coordinating physiological responses in the body.
What system of the body is the secretion of sweat controlled by?
The secretion of sweat is controlled by the nervous system. Specialized nerve fibers called sympathetic nerves stimulate the sweat glands to produce sweat in response to factors such as temperature, physical activity, and emotions.
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
What goal does psychoanalysis primarily attempted to address?
which procedure involves cutting the nerve fibers
