A | B |
Parts of the neuron | dendrites, cell body, axon, axon (synaptic) terminals |
Peripheral nervous system | cranial nerves and spinal nerves |
Neurons | The nervous system is made up of nerve cells called |
Sensory neuron | Transmit impulses from the sense organs (receptors) to the spinal cord and brain |
cerebrospinal fluid | Found in the spinal cord and brain to protect and deliver nutrients |
Motor neuron | Transmit impulses from the brain and spinal cord to effectors (muscle or gland) |
Central Nervous System | Consist of a brain and spinal cord |
Brain | Is a large mass of neurons located in the cranium (skull) |
Cerebrum | Center of control for: voluntary body movements, 5 senses, emotions, and memory |
Cerebellum | Coordinates motor activities and aids in maintaining balance |
Medulla oblongata | Involuntary activities like breathing, digestion and heartbeat |
meninges | three layered covering of the brain and spinal cord |
Spinal Cord | Coordinates activities between the brain and other body structures |
Somatic Nervous System | Consist of nerves that regulate voluntary muscles of the skeleton |
Autonomic Nervous System | Consists of nerves that regulate involuntary actions like heartbeat and gland secretions |
cones | photoreceptors in the eye that recognize color |
Meningitis | Inflammation of the membrane that surrounds the brain and spinal cord |
rods | photoreceptors in the eye that are the most sensitive, but see no color |
blind spot | the area where the optic nerve passes out of the eye (lacking rods and cones) |
left cerebral hemisphere | controls the right side of the body, spoken and written language, logic, reasoning, and scientific and mathematical abilities |
right cerebral hemisphere | controls the left side of the body and is associated with imagination, spatial perception, recognition of faces, and artistic and musical abilities |
concussion | an injury to the brain caused by a blow or jolt to the head that disrupts the normal functioning of the brain |
lobes | frontal, parietal, occipital, and temporal |
corpus callosum | connects the two hemispheres of the brain |
hypothalamus | regulates body temp., water balance, sleep-wake cycles, hunger, thirst, emotions and hormone production |
