If a weight is used, then it rests upon the shoulders, or is held in the hand(s). This is an isolation exercise for the calves; it particularly emphasises the gastrocnemius muscle, and recruits the soleus muscle. [6] Equipment Body weight, dumbbells, barbell, Smith machine or standing calf raise machine. Major variants
In cell biology, adherens junctions (or zonula adherens, intermediate junction, or "belt desmosome" [1]) are protein complexes that occur at cell–cell junctions and cell–matrix junctions in epithelial and endothelial tissues, [2] usually more basal than tight junctions. An adherens junction is defined as a cell junction whose cytoplasmic ...
In anatomy for cardiac muscle, fascia adherens are ribbon-like structures that stabilize non-epithelial tissue. They are similar in function and structure to the zonula adherens or adherens junction of epithelial cells. It is a broad intercellular junction in the transversal sections of an intercalated disc of cardiac muscle anchoring actin ...
Thus, E-cadherin forms adherens junctions that connect the actin cytoskeletons of neighbouring cells. Adherens junctions are the primary force-bearing junctions between epithelial cells and are fundamentally important for maintaining epithelial cell shape and for dynamic changes in shape during tissue development.
The E-cadherin–catenin complex plays a key role in cellular adhesion; loss of this function has been associated with increased invasiveness and metastasis of tumors. [19] The suppression of E-cadherin expression is regarded as one of the main molecular events responsible for dysfunction in cell-cell adhesion, which can lead to local invasion ...
