Intercalated disc Intercalated discs are microscopic identifying features of cardiac muscle. Cardiac muscle consists of individual heart muscle cells (cardiomyocytes) connected by intercalated discs to work as a single functional organ or syncytium.hree types of cell junction make up an intercalated disc — fascia adherens, desmosomes and gap junctions. 1  Fascia adherens are anchoring sites for actin, and connect to the closest sarcomere. 2  Desmosomes stop separation during contraction by binding intermediate filaments, joining the cells together.

Spine Between the vertebrae of the spine are thin regions of cartilage known as the intervertebral discs. Intervertebral discs are made of an outer shell known as the annulus fibrosus and a soft, pulpy region known as the nucleus pulposus in the middle.

Characteristics of Cardiac Muscle Tissue Characteristics of Cardiac Muscle. Cardiac muscle is characterized by striped muscle fibers, connected together by intercolated disks, where the membranes are specialized to allow electrical signals to pass easily. Like smooth muscles, cardiac muscles can remain in contraction for a sustained period.t has characteristics similar to both smooth and skeletal muscle tissue, as well as specialized properties, that allow it to function with fast but sustained contractions, rapid conduction and coordinated movement.

Cardiac Muscle Tissue Cardiac muscle is striated muscle that is present only in the heart. Cardiac muscle fibers have a single nucleus, are branched, and joined to one another by intercalated discs that contain gap junctions for depolarization between cells and desmosomes to hold the fibers together when the heart contracts.

Learn About Muscle Tissue Cardiac Muscle. Cardiac muscle is so named because it is found in the heart. Cells are joined to one another by intercalated discs, which allow the synchronization of the heart beat. Cardiac muscle is branched, striated muscle. The heart wall consists of three layers: epicardium, myocardium, and endocardium.

- Muscle: Cell Junctions. There are several kinds of cell-cell junctions. A description of these can be found here. Cardiac cells are special, amongst the muscle types, because they are connected to each other by intercalated discs-structures that are only found in cardiac muscle cells.These can be seen in this diagram, as darkly staining irregular lines, at 90 degrees to the striped sarcomeric pattern.ardiac cells are special, amongst the muscle types, because they are connected to each other by intercalated discs-structures that are only found in cardiac muscle cells.

Intervertebral disk Intervertebral disk. An intervertebral disk acts as shock absorber between each of the vertebrae in the spinal column by keeping the vertebrae separated when there is impact from activity. They also serve to protect the nerves that run down the middle of the spine and intervertebral disks.he disks are made of fibrocartilaginous material. The outside of the disk is made of a strong material called the annulus fibrosus. Inside this protective covering is a jelly-like substance known as mucoprotein gel. This interior is known as the nucleus pulposus.

- Each intervertebral disc is composed of a band of fibrocarti … lage (annulus fibrosus) that surrounds a gelatinous core (nucleus pulposus). the disc absorbs shocks and helps equalize pressure between the vertebrae when the body movies.t rib 6 joins with transverse process and superior coastal facet of of the vertebrae T6 and with the inferir coastal facet of T5. All of these joints are synnovial plane type joints.

Muscle tissue An isolated cardiac muscle cell, beating. Cardiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium.Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.oordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. This complex mechanism illustrates systole of the heart.

Muscle tissue Coordinated contractions of cardiac muscle cells in the heart propel blood out of the atria and ventricles to the blood vessels of the left/body/systemic and right/lungs/pulmonary circulatory systems. This complex mechanism illustrates systole of the heart.ardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle. These three types of muscle all form in the process of myogenesis. The cells that constitute cardiac muscle, called cardiomyocytes or myocardiocytes, contain only three nuclei.

Describe the structure and role of an intercalated disc.? Best Answer: Intercalated discs are areas where cardiac muscle cells (among a few other cell types) are joined together. These discs contain gap junctions, which are small pores that connect the cytoplasm of one cell to the next.est Answer: Intercalated discs are areas where cardiac muscle cells (among a few other cell types) are joined together.

Intercalated discs Intercalated discs Function/Purpose. The primary role of the cross-bands is to hold the adjacent cells together by providing sites of strong adhesion. The gap junctions promote diffusion of ions between cells and allow waves of depolarization to spread over the entire heart by passing from cell to cell.

Intervertebral Discs The cartilaginous layers of the end plates anchor the discs in place. The intervertebral discs are fibrocartilaginous cushions serving as the spine's shock absorbing system, which protect the vertebrae, brain, and other structures (i.e. nerves). The discs allow some vertebral motion: extension and flexion.

- This is accomplished by inserting a spinal cage or structural bone graft into the vertebral interspace (the area between the two vertebral bodies where the disc is located) and then decorticating an area such as the facet joints and placing bone grafting material.

Cardiac Muscle Intercalated Discs Intercalated Discs and their Functions. Intercalated discs are known to be located inside the cardiac muscles. They are considered to be very important as they work as a connecting link between the two adjacent cardiac cells.he heart of the human beings is made up of cardiac muscles which are different from smooth and skeletal muscles. Inside the cardiac muscles is the intercalated discs which is known to join various adjacent cells together.

All you ever wanted to know about cosmetic serum Like many other skin products, serums are designed to focus on different actions – anti-ageing, brightening, acne prevention, etc. Because of the high concentrations of the active elements, it is common for cosmetic serums to contain only a few active ingredients which provide intensive nutrition for the deeper layers of your skin.

Intercalated discs The cardiac muscle is normally found only in the heart. Here, the myocardial cells usually appear short, branched, and closely interconnected to form a continuous fabric. The cross-bands, however, get heavily stained between the adjacent cells during histological examination of the cardiac tissue.

Intercalated disc Intercalated discs support synchronised contraction of cardiac tissue. They occur at the Z line of the sarcomere and can be visualized easily when observing a longitudinal section of the tissue. Three types of cell junction make up an intercalated disc — fascia adherens, desmosomes and gap junctions.1  Fascia adherens are anchoring sites for actin, and connect to the closest sarcomere. 2  Desmosomes stop separation during contraction by binding intermediate filaments, joining the cells together.olecular, biological, and comprehensive studies have shown that intercalated discs consist for the most part of mixed type adherens junctions, termed composite junctions or areae compositae (singular area composita).
