Anatomy

The vocal folds are tissue structures in the larynx that contribute a large part to voice formation. The vocal folds and the glottis between them regulate both the volume and the pitch of the voice. Will the voice

The peritoneum is a thin skin, also known as the peritoneum, in the area of ​​the abdomen and at the beginning of the pelvis. It is raised in folds and covers the internal organs. The peritoneum supplies the organs and produces a viscous fluid

Synapses are the connection points between nerve cells and sensory, muscle or gland cells or between two or more nerve cells. They are used to transmit signals and stimuli. The stimulus is usually transmitted chemically by means of neurotransmitters

The upper jaw is the largest bone in the skull. It forms the counterpart to the lower jaw.

The bones of the head are called the skull. In medical parlance, the skull is also called "cranium". If, according to the doctor, a process is "intracranial" (tumors, bleeding, etc.), this means "located in the skull".

The temporalis muscle is a human jaw muscle. The skeletal muscle is at the level of the temple. It helps to close the jaw.

Muscle spindles are sensory organs that belong to the group of proprioceptors and recognize the state of stretching and the change in stretching of the skeletal muscles and deliver the generated signals to fast, afferent Ia nerve fibers. Muscle spindles

The spinocerebellar tract is an afferent nerve fiber that supplies the cerebellum with information from the spinal cord. This flow of information includes motor and coordinative stimulation of the muscles, as well as postures

Bone tissue is a particularly strong connective and supporting tissue. It forms the human skeleton. There are between 208 and 212 bones in the body that are made up of bone tissue.

As a complex system, the hormonal system controls the coordination of the functions of all organs of the organism. In humans, over thirty different hormones (messenger substances) are responsible for this. The medical department of endocrinology deals

The knee is the largest joint in the human body. It is composed of different parts and is therefore very complex. Its nature enables people to bend and straighten their knees and is therefore decisive for the sequence of movements

A specific section of DNA is called a gene. It carries hereditary information and, in conjunction with the other genes, controls all of the physical processes. Changes in genes can be both harmless and serious

The two large veins, the superior vena cava (upper vena cava) and the inferior vena cava (lower vena cava), in which the blood of the large body circulation is collected and in the common inflow path sinus venarum cavarum, are referred to as vena cava

Without it, chewing would be impossible: the temporomandibular joint connects the temporal bone with the lower jaw. Disturbances often not only result in pain, but also movement is usually restricted. So that the complaints improve the quality of life of the person affected

Medicine understands the temporal bone to be a symmetrically arranged and extremely detailed brain skull bone. The temporal bone is an important part of the skull base and serves to stabilize the skull and to accommodate sensitive structures

The biceps refers to the biceps brachii muscle. It is found in humans in the upper arm, but can also be found in quadruped mammals (such as dogs). In both cases, one of the things he is responsible for is bending the arm or the front leg

The amniotic fluid is clear, watery body fluid that fills the amniotic cavity - the amniotic sac - and is formed by it. Both the amniotic sac and the amniotic fluid belong to the tissue of the embryo, not to the tissue of the mother.

A trophoblast is a layer of cells. It forms the outer boundary of the blastocyst and is responsible for nourishing the embryo.

Tight junctions are protein networks. They girdle the endothelial tissue of the intestine, the bladder and the brain and, in addition to stabilizing functions, also take on barrier functions. Disturbances of these barrier functions have a negative effect on the

On the back, the thoracodorsal nerve innervates the large back muscle and the large round muscle. Both play an important role in arm movements. Lesions occur, for example, in the context of neuralgic shoulder amyotrophy and the arm plexus
