Terminal cisternae are discrete regions within the muscle cell. They store calcium (increasing the capacity of the sarcoplasmic reticulum to release calcium) and release it when an action potential courses down the transverse tubules, eliciting muscle contraction . [ 2 ]
The number of cisternae in the Golgi stack is dependent on the organism and cell type. [3] The structure, composition, and function of each of the cisternae may be different inside the Golgi stack. These different variations of Golgi cisternae are categorized into three groups; cis Golgi network, medial, and trans Golgi network. [2]
The thinner projections, running horizontally between two terminal cisternae are the longitudinal sections of the SR. The sarcoplasmic reticulum ( SR ) is a membrane -bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells .
Perforating branches of the PCA; The posterior communicating arteries (PCoA) The basal vein; The third (III) cranial nerve, which passes between the posterior cerebral and superior cerebellar arteries; Cerebellopontine angle cistern. It is situated at the cerebellopontine angle – the lateral angle between the cerebellum and the pons. It contains:
In the histology of skeletal muscle, a triad is the structure formed by a T tubule with a sarcoplasmic reticulum (SR) known as the terminal cisterna on either side. [1] Each skeletal muscle fiber has many thousands of triads, visible in muscle fibers that have been sectioned longitudinally. (This property holds because T tubules run ...
T-tubules within the heart are closely associated with the intracellular calcium store known as the sarcoplasmic reticulum in specific regions referred to as terminal cisternae. The association of the T-tubule with a terminal cisterna is known as a diad. [6]
The cistern contains the origin of the abducens nerve (CN VI), [1] [3] the basilar artery [3] and the origin of the basilar artery and of its branches, [1] and the anterior inferior cerebellar artery, and superior cerebellar artery. [1] [3]
The cistern contains the middle cerebral artery (MCA) [2] and its branches, [4] and the two (i.e. superficial and deep) middle cerebral veins (MCVs). [ 2 ] The cistern is subdivided into three compartments: the superficial opercular compartment (SOC) (most superficial), deep opercular compartment (DOC) (intermediate), and cisternal compartment ...
