What is the function of the coracoid plexus?

What is the function of the coracoid plexus?

Key Points. The choroid plexus (ChP) is a secretory tissue found in each of the brain ventricles, the main function of which is to produce cerebrospinal fluid (CSF).

Where is the coracoid plexus located?

ventricular system
The choroid plexus is located in the ventricular system. This series of connecting hollow spaces circulates cerebrospinal fluid. Choroid plexus structures are found within both lateral ventricles as well as the third and fourth ventricles of the brain.

What does the choroid plexus produce?

The choroid plexuses (CPs), located within the ventricles of the brain, produce the cerebrospinal fluid and form an interface between the peripheral blood and the CSF.

What is the choroid plexus and what does it secrete?

The epithelial cells of the choroid plexus secrete cerebrospinal fluid (CSF), by a process that involves the movement of Na(+), Cl(-) and HCO(3)(-) from the blood to the ventricles of the brain. This creates the osmotic gradient, which drives the secretion of H(2)O.

What is a plexus in the brain?

Introduction. The choroid plexus is a complex network of capillaries lined by specialized cells and has various functions. One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain.

How is hydrocephalus diagnosed?

CT scans and MRI scans are often used in combination to confirm a diagnosis of hydrocephalus present from birth (congenital) and hydrocephalus that develops later in children and adults (acquired). These scan the brain in detail.

What is a plexus?

A plexus is a bundle of intersecting nerves, blood vessels, or lymphatic vessels in the human body. These bundles typically originate from the same anatomical area and serve specific areas of the body. Bundles of nerves that form a plexus communicate information to your brain about pain, temperature, and pressure.

How does the choroid plexus work?

One of the primary functions is to produce cerebrospinal fluid (CSF) via the ependymal cells that line the ventricles of the brain. Secondly, the choroid plexus serves as a barrier in the brain separating the blood from the CSF, known as the blood-CSF barrier.

What is the difference between Tela Choroidea and choroid plexus?

The tela choroidea is the thin, highly vascularized, loose connective tissue portion of pia mater that gives rise to the choroid plexus. Thus, it is basically the lamina propria of the ependyma and lies directly adherent to it, without any tissue in between the two 6.

Why does choroid plexus have so many capillaries?

These tight junctions prevent the majority of substances from crossing the cell layer into the cerebrospinal fluid (CSF); thus the choroid plexus acts as a blood–CSF barrier. The choroid plexus folds into many villi around each capillary, creating frond-like processes that project into the ventricles.

Where is the coracoid located in the human body?

The coracoid process (from Greek κόραξ, raven) is a small hook-like structure on the lateral edge of the superior anterior portion of the scapula (hence: coracoid, or “like a raven’s beak”). Pointing laterally forward, it, together with the acromion, serves to stabilize the shoulder joint.

Where is the choroid plexus located in the human body?

Choroid plexus. Choroid plexus is located in the inferior horn of the lateral ventricle, and passes into the interventricular foramen to the third ventricle.

Where are the plexus cords located in the axilla?

In the apex of the axilla, the three plexus cords (lateral, medial, and posterior) form the main terminal nerves of the upper extremity (axillary, musculocutaneous, median, ulnar, and radial).

Why is the coracoid process the lighthouse of the shoulder?

Surgeons often refer to the coracoid process as the “lighthouse of the shoulder” given its proximity to major neurovascular structures such as the brachial plexus and the axillary artery and vein, its role in guiding surgical approaches, and its utility as a landmark for other important structures in the shoulder.
