![]() ![]() The olfactory lobe at the front of the brain controls the sense of smell. ![]() The meninges are the protective membrane covering the brain. What is the protective membrane covering the brain of a fetal pig? The tough outer layer is called the dura mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The delicate inner layer is the pia mater. Three layers of membranes known as meninges protect the brain and spinal cord. Which of the three membranes that protects the brain and spinal cord is found in the middle? ![]() There are three layers of meninges: Dura mater, which is closest to the bone. Meninges are membranes that cover and protect the brain and spinal cord. The brain and spinal cord are protected by bony structures the skull and spinal column. Read More: What is Rapid Application Development used for? In what ways is the brain protected? They’re both cushioned by layers of membranes called meninges and a special fluid called cerebrospinal fluid. What are the two other major ways the brain and spinal cord are protected?īoth the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by a set of ring-shaped bones called vertebrae. Are irregular bones that protect the spinal cord?įor example, the vertebrae, irregular bones of the vertebral column, protect the spinal cord. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. What organ is protected by the spinal column or backbone? The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull. The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. Structure of the spinal cord Externally, the spinal cord is protected by 26 bones called vertebrae, which are sandwiched between cartilage disks to cushion the cord from any jarring caused by bodily movement. How is the spinal cord protected from jerks and injuries? There are three layers of meninges: Dura mater (closest to the bone), Arachnoid loosely around the brain, Pia mater is closely attached to the brain and spinal cord surface. Read More: What is the Food Guide Pyramid used for? Which of the following is a structure that surrounds and protects the spinal cord quizlet? It extends from the brain as a narrowed bore tube, through the spinal canal to the tail. It is covered completely by clear membranes called the meninges. What structure protects the spinal cord in a pig? The surrounding skull and vertebral column provide a strong, protective shelter against damaging blows or bumps. The spinal cord is located within the vertebral canal of the vertebral column. The brain is encased within the cranial cavity of the skull, formed by the securely interlocked cranial bones. How are the brain and spinal cord protected quizlet? The vertebrae protect and support the spinal cord. These are the building blocks of the spinal column. The individual bones of the spine are the vertebrae. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. The spine is made of 33 bones called vertebrae. The spinal cord is protected by bones, discs, ligaments, and muscles. These meninges surround and protect the spinal cord. What are the protective structures of the spinal cord? The vertebral column (skull and spine) and the meninges. What is the spinal cord protected by quizlet? ![]() It circulates through chambers called ventricles and over the surface of the brain and spinal cord. The CSF also carries nutrients in the blood to (and removes waste products from) the brain. The cerebrospinal fluid (CSF) is a clear, watery liquid that surrounds, cushions and protects the brain and spinal cord. ![]()
