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.
What else can I help you with?
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
Do the spinal funiculi contain fiber tracts or neuronal cell bodies?
"The three funiculi contain many fiber tracts. Each fiber tract is composed of axons that have all similar destinations and functions."Citation:Marieb, Elaine N., Patricia Brady Wilhelm, and Jon Mallatt. Human Anatomy. Sixth Edition Media Update. San Francisco: Pearson Education Inc. , 2010. pg. 376.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
What fiber transmits impulses to the central nervous system?
The fiber that transmits impulses to the central nervous system is called an afferent or sensory fiber. These fibers carry sensory information from receptors in the body to the brain and spinal cord, allowing for the perception of different sensations like touch, temperature, and pain.
What do you call the slender nerve fiber?
The slender nerve fiber is called an axon. It is the long, slender projection of a nerve cell that transmits electrical impulses away from the cell body to other neurons, muscles, or glands.
The postganglionic sympathetic fiber originates from?
The postganglionic sympathetic fiber originates from PNS within a ganglion
Which neurons are classified as an adrenergic fiber?
The neuron classified as an adrenergic fiber is the sympathetic postganglionic neuron.
High repetition resistance training?
Does not innervate high threshold motor units and limits the potential for Type IIB muscle fiber hyper
Will fiber help your dogs anal glands?
No the vet needs to clean them out
Which of the following is not an ascending spinal cord nerve fiber tract?
reticulospinal
Damage to this fiber type would lead to a loss of sensory function?
ventral root of a spinal nerve
High repetition resistance training Innervates high threshold motor units?
Does not innervate high threshold motor units and limits the potential for Type IIB muscle fiber hyper
What is contained in the dermis?
in the dermis there is the hair shaft, the follicle, the oil and sweat glands, and the nerve fiber.
What is a long nerve fiber that convey electrical impulses to other cells is called a?
A long nerve fiber that conveys electrical impulses to other cells is called an axon. Axons are part of nerve cells (neurons) and are responsible for transmitting signals to other neurons, muscles, or glands. Some axons can be quite long, extending from the brain or spinal cord to distant parts of the body.
A fiber tract that provides for communication between the cerebrum and the CNS area?
If the fiber tract connects the cerebral cortex and the lower brain or spinal cord then it is referred to as a projection tract.
