Study Notes
Nervous System Functions
- The three main functions of the nervous system are controlling movements, interpreting sensory information, and regulating various bodily functions.
Nervous System Components
- The central nervous system (CNS) is responsible for analyzing sensory information.
- The autonomic nervous system (ANS) controls involuntary actions, such as heart rate, blood pressure, and digestion.
- The somatic nervous system is responsible for transmitting sensory information and controlling voluntary muscles.
Autonomic Nervous System
- The main function of the autonomic nervous system is to regulate involuntary actions and maintain homeostasis.
- The sympathetic nervous system (SNS) prepares the body for emergencies and activates the fight or flight response.
- The parasympathetic nervous system (PNS) promotes relaxation and reduces stress when the body is at rest.
Eye Anatomy and Function
- Rod cells in the retina are responsible for low-light vision.
- The vitreous humor in the eye gives it its shape, maintains its pressure, and allows light to pass through.
- The extrinsic eye muscles (inferior oblique, lateral rectus, medial rectus, superior oblique, and superior rectus) enable the movement of the eye.
