Biology 2 Lab Practical Study Guide
Nervous System and Sensory Organs
• dorsal roots and ventral roots - connect Spinal nerves to the spinal cord
• medulla -responsible for many involuntary functions such as heartbeat and breathing, primary communication pathway between the spinal cord and the rest of the brain,
• cerebellum - receives input from multiple sensory receptor types and uses this information in coordination of complex body movements
• pons- communication between lower and higher brain regions
• midbrain- processes information transfer between the medulla and higher brain areas
• colliculi- process visual and auditory (sound) information
• frontal lobe- responsible for many activities associated with higher brain functioning and information processing
• parietal lobe- this region receives and processes information from the generalized body senses like touch and body position
• occipital lobe- processes and interprets visual information
• temporal lobe- involved in auditory processing, memory, and other functions
• optic nerves- bring visual input from the eyes and enter the ventral brain under the hypothalamus
• pineal gland- functions in skin coloration changes in reptiles and fish, and helps to regulate biological rhythms, including seasonal reproductive cycles, in mammals
• thalamus- responsible for directing important communication, both sensory and motor, between the cerebrum, other brain regions, and the peripheral nervous system
• hypothalamus-controls the hormonal activity of the pituitary gland, regulates numerous other activities ranging temperature control to sleep and rhythms to feeding
• Cerebrospinal fluid- transports nutrients from the blood to the brain and provides a shock-absorbing function that can reduce brain damage due to head injury.
• Pinna- captures and funnels sound waves into the ear
• tympanic membrane- converts air vibrations into tissue vibrations
• malleus, the incus, and the stapes- transmit and further amplify sound vibrations
• oval
