    Four characteristics define smooth muscle tissue cells: they are involuntarily controlled, not striated, not branched, and singly nucleated. The unconscious regions of the brain control visceral muscle through the autonomic and enteric nervous systems. Thus, visceral muscle is involuntarily controlled.

      Smooth muscle lines many parts of the circulatory system, digestive system, and is even responsible for raising the hairs on your arm. In the circulatory system, smooth muscle plays a vital role in maintaining and controlling the blood pressure and flow of oxygen throughout the body.

        Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations. They are called involuntary muscles. Cardiac muscle has branching fibers, one nucleus per cell, striations, and intercalated disks. Its contraction is not under voluntary control

                The individual cardiac muscle cell (cardiomyocyte) is a tubular structure composed of chains of myofibrils, which are rod-like units within the cell. The myofibrils consist of repeating sections of sarcomeres, which are the fundamental contractile units of the muscle cells.

                  Cardiac muscle cells are found only in the heart, and are specialized to pump blood powerfully and efficiently throughout our entire lifetime. Four characteristics define cardiac muscle tissue cells: they are involuntary and intrinsically controlled, striated, branched, and single nucleated

                    Cardiac muscle tissue is one of the three types of muscle tissue in your body. The other two types are skeletal muscle tissue and smooth muscle tissue. Cardiac muscle tissue is only found in your heart, where it performs coordinated contractions that allow your heart to pump blood through your circulatory system.

                            These neurons are able to receive impulses from multiple neurons via dendrites. The dendrites transmit the signals through the neuron via an electrical signal that is spread down the axon. Bipolar neurons: These neurons send signals and receive information from the world

                              A multipolar neuron is a type of neuron that possesses a single axon and many dendrites (and dendritic branches), allowing for the integration of a great deal of information from other neurons. These processes are projections from the neuron cell body.

                                    Another example of hyaline cartilage is the tissue found in the walls of the respiratory tract. This includes the bronchi, the nose, the rings of the trachea, and the tips of the ribs

                                      Where bone ends meet to form a joint, they are covered by hyaline cartilage. This cartilage appears bluish white and glistening in a normal healthy joint. Its primary function is to provide some cushioning and minimize friction between the bone ends.

                                            Elastic cartilage provides strength, and elasticity, and maintains the shape of certain structure such as the external ear. It has a perichondrium.

                                              Elastic cartilage , sometimes referred to as yellow fibrocartilage, is a type of cartilage that provides both strength and elasticity to certain parts of the body, such as the ears. Within the outer ear, it provides the skeletal basis of the pinna, as well as the lateral region of the external auditory meatus.

                                                    Fibrocartilage provides the tough material of the intervertebral discs; the intraarticular cartilages of the knee, wrist and temporo-mandibular joints; the articular cartilage of the temporo-mandibular joint and of the joint between the clavicle and the sternum.

                                                      Fibrocartilage is the tough, very strong tissue found predominantly in the intervertebral disks and at the insertions of ligaments and tendons; it is similar to other fibrous tissues but contains cartilage ground substance and chondrocytes.
