Question | Answer |
Central nervous system | the complex of nerve tissues that controls the activities of the body |
Peripheral nervous system | the nervous system outside the brain and spinal cord |
Brain | an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity |
Cerebrospinal fluid | clear watery fluid that fills the space between the arachnoid membrane and the pia mater |
Cerebrum | the principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, left and right, separated by a fissure |
Lobs | a roundish and flattish part of something, typically each of two or more such parts divided by a fissure, and often projecting or hanging |
Cerebellum | the part of the rain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity |
Brain stem | the central trunk of the mammalian brain, consisting of the medulla oblongata, pons, and midbrain, and continuing downward to form the spinal cord |
Spinal columms | the spine; the backbone |
Vertebrae | each of the series of small bones forming the backbone, having several projections for articulation and muscle attachment, and a hole through which the spinal cord passes |
Spinal cord | the cylindrical bundle of nerve fibers and associated tissue that is enclosed in the spine and connects nearly all parts of the body to the brain, with which it forms the central nervous system |
Neurons | a specialized cell transmitting nerve impulses; a nerve cell |
Sensory neurons | different kind of neurons |
Motor neurons | a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland |
Dendrite | physiology a short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body |
Impulse | physics a force acting briefly on a body and producing a finite change of momentum |
Axon | the long threadlike part of a nerve cell along which impulses are conducted from the cell body to other cells |
Synapse | a junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter |
Neurotransmitters | the electrical impulse arrives at the synapse, the electricity causes chemicals |
Myelin sheath | the axons protective covering |
Somatic nervous system | it controls your skeletal movements and helps your body adjust to its external environment |
Autonomic nervous system | the part of the nervous system responsible for control of the bodily functions not consciously directed, such as breathing, the heartbeat, and digestive processes |
Reflexes | an action that happens before the brain has time to think about the action |
Olfactory receptor cells | detect the particles and send impulses to the olfactory nerve |
Epidermis | the outer skin |
Dermis | the inner layer of skin |
Memory | the ability to remember |
Short-term memory | stores of information only temporarily |
Long-term memory | can store information for months, years, or even for a lifetime |
Hippocampus | the seems to be aria inside of the lobe |
Declarative or Procedural | another term of long-term memory |
Electroencephalograph | a machine used for electroencephalography |
Hormones | a chemical messenger from the endocrine system |
Endocrine glands | special group of cells that make chemicals, such as hormones, for the bode |
Target cells | a group of cells that can be affected by a certain hormone |
Hypothalamus | a group of special cells near the base of the brain that helps to regulate parts of the body |
Pituitary glad | the master glad of the endocrine system |
Epilepsy | a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain |
Multiple sclerosis | a chronic, typically progressive disease involving damage to the sheaths of nerve cells in the brain and spinal cord, whose symptoms may include numbness, impairment of speech and of muscular coordination, blurred vision, and severe fatigue |
Parkinson’s disease | a disorder of the nervous system that damages brain cells that control movements |
Alzheimer’s disease | disorder of the nervous system; affects a person’s mind, often decreasing a person’s short-term memory, ability to learn new information, and ability to reason |
