What two structures directly receive an electrical impulse from the sinoatrial node?
Only one receives the signal from the SA Node and that is the A-V node.There are specialized areas of cardiac muscle tissue (1%) in the heart that are autorhythmic (self-exciting). These cells compose the CCS and are responsible for initiating and distributing cardiac (electrical) impulses throughout the heart muscle (i.e. cause the heart to beat). These specialized areas together coordinate the events of the cardiac cycle, which makes the heart an effective pump.A. Components of CCS:1. Sinoatrial Node (S-A Node):located in right uppermost atrial wall and called the PACEMAKER = self-exciting tissue (rhythmically and repeatedly [60-100 per minute] initiates cardiac impulses)2. Atrioventricular Node (A-V Node): located in interatrial septum; serves as a delay signal that allows for ventricular filling. This one will act as a back up pacemaker if needed. It is also called the Bundle of His.3. Right and left bundle branches lead downward through interventricular septum toward apex, and impulse finally reaches...4. Purkinje Fibers (Conduction Myofibers), large diameter conduction myofibers; located within the papillary muscles of the ventricles; conduct the impulse into the mass of ventricular muscle tissue.
Cells self destruct through a process called?
apoptosis. During apoptosis, cells undergo a controlled sequence of events leading to their self destruction. This process plays a crucial role in maintaining tissue homeostasis and eliminating damaged or unwanted cells from the body.
What are the potential health implications of having excess fatty breast tissue?
Excess fatty breast tissue can increase the risk of health issues such as breast cancer, heart disease, and obesity-related conditions. It may also impact self-esteem and mental well-being. Regular exercise and a healthy diet can help reduce excess fat in the breasts and lower these risks.
Which of the following was an important quality of protocells?
An important quality of protocells was their ability to self-assemble from simple molecules and exhibit some basic properties of living cells, such as maintaining an internal environment and undergoing simple processes like growth and division. These early structures laid the foundation for the evolution of more complex cellular life.
What structural component of a cell membrane is involved when a cell is recognized as belonging to a specific tissue?
Glycoproteins and glycolipids are involved in cell recognition within specific tissues. These molecules, which are carbohydrates attached to proteins or lipids on the cell membrane, help cells communicate with each other and identify self from non-self.
Which of the following heart structures is self exciting tissue?
sinoatrial node of the heart.
What portion of the heart organ is composed of self-exciting tissue?
# Cardiac muscle tissues such as the sinoatrial node are self exciting. This is because they do not rely on any outside resources to stimulate the heart. This is what gives the heart the pace making rhythm and keeps the heart beating.
What tissue doesnt repair its self but is replaced with scar tissue?
Muscle tissues

What is the least important function of muscle tissue?
the least important function is the wall of the tissue it self!
Who argued that the self consists of conscious and unconscious levels?
Sigmund Freud
Is Switzerland homogeneous?
No, it is decentralised. Switzerland consists of cantons, which are largely self-governing.
