Neurohypophysis: Development, Functioning And Diseases

The neurohypophysis , also called the posterior lobe of the hypophysis or posterior pituitary, is a structure that is responsible for storing and releasing two hormones: vasopressin and oxytocin. These hormones regulate the secretion of water, and the mammary glands and uterine contractions, respectively. This structure is part of the hypophysis or pituitary gland, belonging

Brain Fissures And Their Characteristics

The  fissures of the brain are the grooves and folds present on the surface of the cerebral cortex. They are the part that gives the brain its wrinkled appearance ; and its function is fundamental in the development of human intelligence and our higher mental capacities. Fissures of the brain can be divided into convolutions

Reflex Arc: Components, Types And Functions

The  reflex arc  is a neural pathway that is responsible for producing automatic and unconscious movements, known as reflex acts. Unlike most neural pathways, in almost all animal species, these do not pass through the brain. Rather, the responses are created in the spinal cord. This allows reflex actions to take place much faster than

Myoclonus: Symptoms, Types, Causes And Treatment

The myoclonus or myoclonus are contractions or sudden jerks of a muscle or group of muscles. People who experience them cannot control these spasms, that is, they are involuntary. The term myoclonus can be divided into “mio”, which means muscle, and “clonies” or “clones” which mean “jerk.” Both muscle contraction (called positive myoclonus) and sudden, uncontrolled

Pituitary: Characteristics, Functions, Pathologies

The pituitary gland or pituitary gland is an endocrine gland that secretes hormones responsible for regulating the body’s homeostasis. It is responsible for regulating the function of other glands of the endocrine system and its operation is conditioned by the hypothalamus, a region of the brain. It is a complex gland located in a bony
