A capsule, in anatomy, is a cover or envelope partly or wholly surrounding a structure. Anatomy (from the Greek anatomia, from ana separate apart from and temnein, to cut up cut open is a branch of Biology that is the consideration Types of capsules include:

• the shell of an egg (biology)
• joint capsules - every diarthrodial joint possesses a fibrous or ligamentous capsule, lined with synovial membrane, attached to the adjacent ends of the articulating bones
• the sac which encloses the crystalline lens of the eye
• Glisson's capsule, a thin areolar coat of fibrous tissue lying inside the tunica serosa of the liver
• Bowman's capsules (or glomerular capsules) in the kidney substance
• the renal capsule (also known as Gerota's fascia), a tough fibrous layer surrounding the kidney and covered in a thick layer of perinephric adipose tissue
• the suprarenal capsules, two small flattened organs in the epigastric region
• the internal, external and extreme capsules of the brain
• the outer surface of a benign tumor

In most Birds and Reptiles an egg ( Latin ovum) is the Zygote, resulting from Fertilization of the Ovum. An articular capsule (or joint capsule) is an envelope surrounding a Synovial joint. Synovial joints (or diarthroses, or diarthroidal joints) are the most common and most moveable type of Joints in the human body Eyes are organs that detect Light, and send signals along the Optic nerve to the visual areas of the brain Francis Glisson (1597– October 14, 1677) was a British Physician, Anatomist, and writer on medical subjects The Bowman's capsule (other names capsula glomeruli glomerular capsule is a cup-like sac at the beginning of the tubular component of a Nephron in the mammalian The kidneys are complicated organs that have numerous biological roles The renal capsule is a tough fibrous layer surrounding the Kidney and covered in a thick layer of perinephric Adipose tissue. "Adipose" redirects here For the Doctor Who monster see " Partners in Crime " The internal capsule is an area of White matter in the Brain that separates the Caudate nucleus and the Thalamus from the Lenticular nucleus The external capsule is a series of White matter fiber tracts in the Brain. The extreme capsule is a series of White matter fiber tracts in the Brain. The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain A benign tumor is a Tumor that lacks all three of the Malignant properties of a Cancer.
