The seven chakras run in a vertical line from the base of your spine to the top of your head. Each one corresponds to a specific spot on the body and is traditionally linked to nearby organs and nerve networks. The system originated in the Vedas, a collection of Hindu hymns dating to roughly 1500 to 1000 BCE, and was further developed in the Upanishads between 800 and 400 BCE. Here’s exactly where each chakra sits and what part of the body it relates to.
Root Chakra (Muladhara)
The root chakra is located at the very base of the spine, in the area between the anus and the genitals known as the perineum. A cadaveric study published in the International Journal of Yoga found that this location closely maps to the inferior hypogastric plexus, a triangular network of nerves that supplies the pelvic organs: the rectum, bladder, uterus, and testes. The four “petals” traditionally depicted in illustrations of this chakra correspond to four branches of that nerve plexus, each one serving a different pelvic organ.
Because of its position at the foundation of the spine, the root chakra is associated with feelings of stability, safety, and physical grounding.
Sacral Chakra (Svadhisthana)
The sacral chakra sits in the lower abdomen, roughly two finger-widths below the belly button. It overlaps with the sacrum, the triangular bone at the base of the lumbar spine. Physically, this area houses the reproductive organs, bladder, kidneys, and adrenal glands. The triangular shape associated with this chakra in traditional imagery mirrors the shape of the womb, tying it to themes of creativity and sexuality.
Pain or tension in the lower back and reproductive health issues are sometimes described in yoga traditions as signs of imbalance in this energy center.
Solar Plexus Chakra (Manipura)
The third chakra is located in the upper abdomen, just behind the stomach and the diaphragm (the dome-shaped muscle beneath your lungs). This is the anatomical solar plexus, a dense cluster of nerves that sits in front of the descending abdominal aorta, the body’s largest blood vessel.
The solar plexus is a major relay station for the gut. It sends nerve impulses to the stomach, liver, gallbladder, pancreas, spleen, kidneys, small intestine, and the first two-thirds of the large intestine. That heavy concentration of nerve tissue is why a blow to this area can knock the wind out of you, and it’s also why the Manipura chakra is linked to digestion, metabolism, and that visceral “gut feeling” people describe when making decisions.
Heart Chakra (Anahata)
The heart chakra is located at the center of the chest, behind the sternum, at roughly the height of the thymus gland. The thymus is a small organ that plays a key role in immune function, especially during childhood. This chakra is associated with the heart, lungs, and circulatory system.
Its central position in the seven-chakra lineup is significant. It sits between the three lower chakras (which relate to physical and emotional survival) and the three upper chakras (which relate to communication, perception, and consciousness). In yoga philosophy, it serves as the bridge between body and mind.
Throat Chakra (Vishuddha)
The fifth chakra is positioned at the throat, near the cervical spine, with its surface point in the pit of the throat. It corresponds physically to the thyroid gland, a butterfly-shaped gland in the neck that produces hormones controlling growth, metabolism, and energy levels. The larynx (voice box) also falls within this zone.
The connection between the throat chakra and self-expression isn’t purely symbolic. Chronic tension in the throat and neck muscles is a well-known physical response to stress, and the thyroid is sensitive to prolonged emotional strain. In yogic tradition, fear of speaking out is said to directly affect this energy center.
Third Eye Chakra (Ajna)
The sixth chakra is located at the center of the forehead, between the eyebrows. In the physical body, it corresponds to structures deep in the brain: the hypothalamus, the pituitary gland, and the pineal gland. Some traditions describe its internal position as roughly four inches behind the center of the eyebrows, placing it near the center of the brain.
The pituitary gland is often called the “master gland” because it regulates hormone production throughout the entire endocrine system. The pineal gland produces melatonin, which governs your sleep-wake cycle. The hypothalamus links the nervous system to the endocrine system. Together, these three structures control much of the body’s hormonal signaling, which is why the Ajna chakra is traditionally associated with perception, intuition, and mental clarity. The eyes, ears, and nose also fall under its domain.
Crown Chakra (Sahasrara)
The seventh and final chakra sits at the very top of the head, at the crown where the skull meets the upper spine. Like the third eye chakra, it is associated with the pineal gland, pituitary gland, and hypothalamus. The pineal gland’s role in producing melatonin connects it to cycles of sleep, wakefulness, and (in yogic thought) states of higher consciousness.
Unlike the other six chakras, the crown chakra isn’t tied to a specific organ system or nerve plexus below the neck. Its associations are entirely cerebral. In traditional depictions, it is shown as a thousand-petaled lotus, symbolizing an expansive, open connection rather than a localized physical function.
How the Chakras Map to the Nervous System
One pattern worth noticing is that the chakra locations closely follow the major nerve plexuses of the body. The root chakra maps to the pelvic nerve plexus. The solar plexus chakra maps to the actual solar plexus. The throat chakra aligns with the pharyngeal plexus and the nerves serving the thyroid. The upper chakras correspond to the brain’s core regulatory glands.
This isn’t coincidence. The ancient texts describe chakras as wheels or vortexes of energy along the spinal column, and the spinal column is exactly where the central nervous system branches out to serve different regions of the body. Whether you approach chakras as spiritual energy centers, as a meditative framework for body awareness, or as a poetic map of the nervous system, the locations are consistent: they mark the points where major nerve activity is concentrated, running from the pelvic floor to the crown of the head.
