Study Notes
Nervous System Functions
- The nervous system's integrative function involves analyzing sensory input, storing information, and making decisions.
Autonomic Nervous System (ANS)
- ANS consists of motor fibers that transport nerve impulses from the Central Nervous System (CNS) to smooth and cardiac muscles, as well as glands.
Neuron Structure
- The axon is the part of a neuron responsible for conducting impulses away from the cell body.
Nerve Impulse Communication
- Nerve impulses are communicated between nerve cells through structures known as synapses.
Nerve Cell Collections
- Collections of nerve cell bodies located outside the CNS are referred to as ganglia.
Central Nervous System (CNS)
- CNS is comprised of the brain and spinal cord, serving as the primary control center for the body.
Neurotransmitters
- Neurotransmitters are substances released at axon terminals that propagate nerve impulses.
Brain Stem
- The brain stem is composed of three main parts: the midbrain, pons, and medulla oblongata.
Vital Centers
- The medulla oblongata houses essential centers that control heart rate, respiration, and blood pressure.
Cerebral Hemispheres
- The longitudinal fissure separates the two cerebral hemispheres of the brain.
Cerebrum Function
- The cerebrum is often described as the "executive suite" of the brain, involved in decision-making and higher brain functions.
Brain Surface Features
- Sulci are shallow grooves on the surface of the cerebral cortex, contributing to the brain's complex structure.
Hypothalamus Role
- The hypothalamus acts as the body's thermostat, regulating temperature and maintaining homeostasis.
Cerebrospinal Fluid Composition
- Normal cerebrospinal fluid should not contain red blood cells, which indicates a healthy condition.
