The main parts of the human brain are the brain stem, the cerebellum, the diencephalon, and the cerebrum, which is divided into lobes.
Producing speech requires the synchronized operation of several cortical centers.
The central nervous system consists of the brain and the spinal cord, the peripheral nervous system consists of nerves and ganglia.
The spinal cord is the part of the central nervous system running inside the spinal column from which spinal nerves branch out.
Bones of the lower limbs are connected to the trunk by the pelvis.
Bones of the upper limbs form the pectoral girdle and the arms.
Systemic circulation carries oxygenated blood from the heart to the body, while pulmonary circulation carries oxygenated blood from the lungs to the heart.
This animation introduces the most important organ systems of the human body.
The Hypothalamic-pituitary axis is the regulating center of our endocrine system.
The knee joint is made up by the femur, the tibia and the kneecap.
The limbic system plays an important role in forming emotions and in learning.
Scoliosis is a medical condition in which a person's spine has a lateral deviation.
This animation shows the symptoms and treatment of secretory otitis media.
Neurons are cells specialized for transmitting electric signals.
The reflex triggered by the stretching of the thigh extensor muscle is the patellar reflex.
Neurons transmit electrical signals via chemical and electrical synapses.
The ear converts the vibrations of air into electric signals which are then processed by the brain.
The heart is the central pump of the cardiovascular system beating several billion times over our lifetime.
Organs that detect signals of the environment or of the body and transmit them to the brain as nerve impulses.
The two main parts of the central nervous system, the brain and the spinal cord are protected by the skull and the spinal column.
Human bones are joined together by cartilaginous or synovial joints, sutures or they can fuse together.
This animation demonstrates the internal structure of the brain.
During the evolution of vertebrates the relative development of brain areas has changed.
