What is the difference between a ganglion and a plexus?
A ganglion is a cluster of nerve cell bodies located outside the central nervous system, typically along a nerve pathway. A plexus, on the other hand, is a network of intersecting nerves, typically formed by the branching and merging of nerves from different spinal nerve levels. Ganglia are collections of nerve cell bodies, while plexuses are networks of nerve fibers.
What are nerve ganglions give examples?
A ganglion is a cluster of nerve cells found in the peripheral and central nervous system. The main components of the ganglion are a cell body called the somata and associated dendritic structures. Ganglia often connect with each other to form a complex network called the plexus. In addition to the ganglion of the peripheral nervous system, there are also parts of the brain that contains a cluster of interconnected nuclei called the "basal ganglia" or "basal nuclei". Basal ganglia are found in the cerebral cortex, thalamus and brainstem and is associated with several key functions including motor control, emotions, cognition and learning. There are major nerve plexuses (off the spinal cord) 1. Cervical plexus - innervates the diaphragm "The primary danger of a 'broken neck' is that the phrenic nerve may have been severed, leading to paralysis, cessation of breathing and death …" 2. Brachial plexus 1. Axillary nerve 2. Radial nerve 3. Median nerve 4. Musculocutaneous nerve 5. Ulnar nerve These move arm and fingers 3. Lumbar plexus Movement of legs 4. Sacral plexus Movement of feet
The phrenic nerve is a member of which nerve plexus?
Cervical plexus....
What type of nerve is the optic nerve?
ganglion cells
The median nerve is a member of which nerve plexus?
The median nerve is a member of the brachial plexus. It is formed by contributions from the lateral and medial cords of the brachial plexus, primarily from spinal nerve roots C6, C7, C8, and T1.
Is there a difference between ganglion and ganglia?
Yes, there is a difference between ganglion and ganglia. Ganglion refers to a single nerve cell cluster, while ganglia is the plural form, referring to multiple nerve cell clusters.
The largest nerve of the sacral plexus is the?
The largest branch of the sacral plexus is the sciatic nerve, the thickest and longest nerve in the body.
What primary nerve that controls breathing is found in which nerve plexus?
The nerve that control the larynx during breathing is the Vagus Nerve.
What are the four nerve plexuses?
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
What are the two primary nerve plexuses regulating digestive function?
The two primary nerve plexuses regulating digestive function are the myenteric plexus (Auerbach's plexus) and the submucosal plexus (Meissner's plexus). They are part of the enteric nervous system and play important roles in controlling gastrointestinal motility, secretion, and blood flow.
The median nerve is a member of which neve plexus?
Branchial plexus
What is the nerve plexus from which the sciatic nerve originates from?
The sciatic nerve originates from the sacral plexus, specifically from the nerve roots L4 to S3. It is the largest nerve in the body and supplies the lower limb with both motor and sensory functions.
