Study Notes
Nervous System
- Motor neurons carry response signals to effectors
- Somatic nervous system carries signals from the brain to muscles for movement
- Afferent division carries signals from the senses to the brain
Eye and Vision
- Rods and cones are light-sensitive cells in the retina, sending visual signals to the brain
- Iris is responsible for controlling pupil size
- Ciliary body is responsible for shaping the lens for focusing
- Choroid layer supplies oxygen and nutrients to the retina
Hearing and Balance
- Cochlea is responsible for converting sound waves into electrical signals
- Vestibule in the inner ear is responsible for balance and spatial orientation
- Semicircular canals in the inner ear are responsible for detecting rotational movements
Sensory Receptors
- Thermoreceptors detect changes in temperature
- Mechanoreceptors respond to mechanical pressure or distortion
- Chemoreceptors detect specific chemicals, like taste and smell
- Nociceptors respond to pain stimuli
Meninges and Cerebrospinal Fluid
- Pia mater is the deepest and closest layer to the brain and spinal cord
- Cerebrospinal fluid (CSF) cushions and protects the brain and spinal cord
- Arachnoid mater and dura mater are the middle and outer layers of the meninges
Autonomic Nervous System
- Controls basic functions and reflexes
- Prepares the body for stress, increasing heart rate and redirecting blood flow
Neuron Structure
- Dendrites receive signals from other neurons
- Axon transmits signals away from the cell body to other neurons or muscles
