CARDIAC MUSCLE STRUCTURE AND FUNCTION | Clinical Gate

Jun 21, 2015·In order to work as an effective contractile unit and to permit electrical activity to spread across heart muscle the individual muscle cells must be both physically joined together and electrically connected. This is achieved by the presence of ‘intercalated discs’—sites of apposition and thickening of the sarcolemma of adjacent cells.

Podosome initiation and assembly is highly regulated, both spatially and temporally. Dendritic cells best exemplify the temporal regulation of podosome formation. Following activation by an antigen or inflammatory cytokine, immature dendritic cells have a small window of time, roughly 6 hours, during which podosomes are able …

Mar 20, 2003·Junctions Between Cells. In many animal tissues (e.g., connective tissue), each cell is separated from the next by an extracellular coating or matrix.. However, in some tissues (e.g., epithelia), the plasma membranes of adjacent cells are pressed together.Four kinds of junctions occur in vertebrates: Tight junctions; Adherens junctions

Trachea - an overview | ScienceDirect Topics

The trachea is a cartilaginous tube formed by a series of tracheal cartilages, joined together by annular ligaments (Figs. 4-13, 4-15 and 6-9).These cartilages give the trachea rigidity and prevent its collapse. In the mouse, the trachea has about 15 cartilages with an approximate internal diameter of 1.5 mm.The C-shaped cartilages are open dorsally.

Frontiers | Satellite cells in human skeletal muscle ...

Skeletal muscle satellite cells are considered to play a crucial role in muscle fiber maintenance, repair and remodeling. Our knowledge of the role of satellite cells in muscle fiber adaptation has traditionally relied on in vitro cell and in vivo animal models. Over the past decade, a genuine effort has been made to translate these results to humans under physiological conditions.

The immune system

Oct 31, 2016·All cells are able to commit suicide and this type of cell death is called apoptosis; it is very important in development and in the immune system. In the thymus, where, as explained above, most of the lymphocytes that audition for a role as useful effector cells die, it …

Cardiac Muscle Tissue | Interactive Anatomy Guide

Oct 04, 2017·Cardiac muscle cells have a branched shape so that each cell is in contact with three of four other cardiac muscle cells. Together all of the cardiac muscle cells in the heart form a giant network connected end to end. At the ends of each cell is a region of overlapping, finger-like extensions of the cell membrane known as intercalated disks.

A tissue is a group of multiple similar cells (these cells can either be of the same cell type or can consist of a few related cell types) that work together to perform a specific function. An organ is an anatomically distinct structure of the body composed of two or more tissue types that performs one or more specific functions.

Mar 13, 2017·As cells migrate, Fat2 signals to Lar in the cell behind it, which causes that cell to extend its leading edge, tucking under the cell in front of it. In response, Lar signals back to the cell ahead, which retracts its trailing edge. Step-by-step, the neighboring cells work together in this coordinated fashion to move the entire tissue.

MCB 32 Introductory Human Physiology

Muscle cells joined by gap junctions can transmit electrical information in the form of ions directly from cell to cell, so that the action potential proceeds not just down the length of a single cell, but through all the muscle cells in the tissue. ... This is the basis for the coordinated contraction of the heart, and for the process to …

Cardiac Muscle Tissue | Boundless Anatomy and Physiology

Cardiac muscle, composed of the contractile cells of the heart, has a striated appearance due to alternating thick and thin filaments composed of myosin and actin. Actin and myosin are contractile protein filaments, with actin making up thin filaments, and myosin contributing to thick filaments. Together…

The heart’s job is to keep oxygen rich blood flowing through the body. All the body’s cells need a constant supply of Oxygen, especially those in the brain. The brain cells like only four to five minutes after their oxygen is cut off, and death comes to the entire body. 2. The heart is a specialized muscle that serves as a pump.

Gap junction - Wikipedia

Gap junctions are a specialized intercellular connection between a multitude of animal cell-types. They directly connect the cytoplasm of two cells, which allows various molecules, ions and electrical impulses to directly pass through a regulated gate between cells.. One gap junction channel is composed of two connexons (or hemichannels), which connect across the intercellular space.

Lesson Explainer: Animal Tissues | Nagwa

We commonly define a tissue as a group of cells that work together to perform a specific function. Cells make up tissues, which make up organs, which make up organ systems, which make up organisms. Since tissues are made of cells, the types of cells found in a tissue determine the role that this tissue plays.
