Fetal Circulation and Baby's First Breath

Annals of Medical School discusses how the circulation is different before birth so that blood from the mother can oxygenate the growing fetus, and how this changes as a response to the boost of oxygen when the newborn baby first breathes.

How the Body Works : The Regions of the Brain

The Regions of the Brain

The brain has three major functional and anatomical parts--the forebrain, midbrain and hindbrain. The forebrain consists of the cerebral hemispheres, thalami, hypothalamus and limbic system. The top inch of the brain stem is the midbrain. The hindbrain includes the cerebellum, the pons and the medulla. Other parts of the brain's anatomy include: the cerebral cortex, a thin layer of nerve cells on the surface of the cerebral hemispheres; the cerebrum, composed of many millions of nerve fibers, is covered by the cerebral cortex; the corpus callosum, a C-shaped collection of fibers, forms a bridge between the left and right hemispheres; the thalamus, which relays and receives messages to and from other areas of the brain; the limbic system, concerned with memory and emotion; the cerebellum, the largest part of the hindbrain and responsible for balance and the fine control of muscle movements; and the hypothalamus, which lies below the third ventricle of the brain, and regulates many of the body's functions and the activity of the pituitary gland.

How the Body Works : The Auditory Pathways

The Auditory Pathways

The auditory center, in the brain, shown above in red, is concerned with hearing. Although shown here on the outer surface of the brain, most of this area lies within the temporal lobes and is found within the surface of the cerebral cortex on both sides of the brain. The auditory pathways begin in the nerve fibers of the organ of Corti in the inner ear, where sound waves are converted to nerve impulses. These impulses travel in the auditory nerve to the auditory cortex of the brain. During their passage to the auditory center, some of the auditory nerve fibers cross in the brain stem. This results in the sound which enters one ear passing to both cortices. The impulses are relayed in the lateral lemnisci and from there, via the medial geniculate nuclei, to the auditory cortices in the temporal lobes of the brain, where sound is perceived.
