Nervous & Reproductive System
The Nervous System
Function
Responsible for the control of the body and communication among its parts.
Central and Peripheral systems
Parts: Brain and Spinal Cord
Peripheral: Cells of the sensory nervous system send information to the CNS from internal organs or from external stimuli. Motor nervous system cells carry information from the CNS to organs, muscles, and glands.
Parts: All peripheral nerves (Sensory and Motor)
Cerebral hemispheres- Each of the two parts of the cerebrum (left and right) in the brain of a vertebrate.
Diencephalon- The posterior part of the forebrain, consisting of the hypothalamus, thalamus, metathalamus, and epithalamus; the subthalamus is often recognized as a distinct division.
Brain stem- regulation of heart rate, breathing, sleeping, and eating.
Cerebellum- receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. And coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth, balanced muscular activity.
Disorders
- Difficulty walking, stiff muscles, slow shuffling gait, muscle rigidity, involuntary movements, problems with coordination, difficulty standing, muscle twitch, difficulty with bodily movement, or slow bodily movement.
