The rough endoplasmic reticulum works in concert with the Golgi complex to target new proteins to their proper destinations. The second method of transport out of the endoplasmic reticulum involves areas called membrane contact sites, where the membranes of the endoplasmic reticulum and other organelles are held closely together, allowing the ...
Masses of rough endoplasmic reticulum also occur in some non-neuronal cells, where they are referred to as ergastoplasm, basophilic bodies, [1] or chromophilic substance. [4] While these organelles differ in some ways from Nissl bodies in neurons, [5] large amounts of rough endoplasmic reticulum are generally linked to the copious production of ...
The rough endoplasmic reticulum is so named because the cytoplasmic surface is covered with ribosomes, giving it a bumpy appearance when viewed through an electron microscope. The smooth ER appears smooth since its cytoplasmic surface lacks ribosomes.
Abundant rough endoplasmic reticulum combined with a well-developed Golgi apparatus makes plasma cells well-suited for secreting immunoglobulins. [4] Other organelles in a plasma cell include ribosomes, lysosomes, mitochondria, and the plasma membrane. [citation needed]
The nucleolus within the nuclear envelope is the location of ribosome synthesis. The destination of synthesized ribosomes for protein translation is rough endoplasmic reticulum (rough ER), which is connected to and shares the same membrane with the nucleus. The Golgi body is also near the rough ER for packaging and redistributing. Likewise ...
In electron micrographs of gonadotropic cells, the rough endoplasmic reticulum is prominent and forms dilated stacks, and the Golgi apparatus are also clearly visible. Cytoplasmic granules within gonadotropic cells are responsible for producing FSH and LH. In most gonadotrophs, the cytoplasm contains both FSH and LH, but there are some ...
Rough endoplasmic reticulum – A section of the endoplasmic reticulum on with the protein manufacturing organelle i.e. ribosomes are attached is termed as rough endoplasmic reticulum which give it a "rough" appearance (hence its name). [6] Its primary function is the synthesis of enzymes and other proteins.
The soma of a neuron (i.e., the main part of the neuron in which the dendrites branch off of) contains many organelles, including granules called Nissl granules, which are composed largely of rough endoplasmic reticulum and free polyribosomes. [5] The cell nucleus is a key feature of the soma.
