Study Notes

Levels of Analysis and Behavior

Key levels of analysis include social, organ, neural, circuit, cellular, synaptic, and molecular.
Behavior can be categorized as overt (observable movement) or covert (internal processes like cognitive functions).
Operational definition: Behavior is a physiological response.
Main types of behaviors: automatic (body functions), homeostatic (sleep, consumption), higher-order cognition (memory, language).

Nervous System Overview

The nervous system regulates behavior through a reciprocal relationship with the environment.
Neuroplasticity allows the nervous system to adapt based on experiences and behaviors.
Basic functions of the nervous system: information reception, processing, storage, and physiological response production.
Behavior supports survival and species propagation.

Functional Neuroanatomy

Focus areas: invertebrate vs vertebrate nervous systems, central and peripheral nervous system subdivisions.
Central nervous system (CNS) includes the brain and spinal cord; peripheral nervous system (PNS) connects the CNS to the body.

Invertebrate Nervous System Features

Lacks spinal cord or bony structures; consists of ganglia (neuron groups).
Some exhibit primitive brain structures; larger, free neurons compared to vertebrates.
Studied species: sea anemones, sea stars, earthworms, Aplysia.

Common Features of Vertebrate Nervous System

Develops from a hollow dorsal tube; shows bilateral symmetry and segmentation.
Includes separate systems for visual, memory, and language functions.
Localization of function is present, with specific brain regions supporting different functions.
Hierarchical control exists with higher-order areas having more essential functions.

Divisions of the Nervous System

Afferents: nerves conveying messages to the CNS (approach).
Efferents: nerves sending messages from the CNS to the body (exit).
CNS dominates control and information processing, while PNS encompasses all nerves outside the skull and spine.

Brain Structure

Four main lobes: frontal, parietal, temporal, and occipital.
Sulcus: small grove; fissure: large groove; gyrus: bulging convolutions.
Lissencephalic brain lacks folds; folds increase space for neurons, enhancing processing capacity.

Spinal Cord Anatomy

Composed of 33 vertebrae categorized as cervical, thoracic, lumbar, sacral, and coccygeal for support and mobility.
Meninges consist of three protective layers: dura mater (outer), arachnoid mater (middle), pia mater (inner).
Gray matter contains cell bodies; white matter contains myelinated axons.
Dorsal root handles sensory information; ventral root manages motor information.

PNS: Somatic Nervous System

Voluntary control system connecting the CNS to skeletal muscles; includes both afferent and efferent nerves.
Somatic nerves release acetylcholine (Ach).

Cranial Nerves

Twelve pairs responsible for head and neck sensory and motor functions, with specific roles:
- Olfactory (smell), Optic (vision), Ocular, Trochlear, Abducens (eye movement), Trigeminal (mixed), Facial (mixed), Vestibulocochlear (hearing), Glossopharyngeal (mixed), Vagus (mixed), Spinal accessory (motor), Hypoglossal (motor).

PNS: Autonomic Nervous System

Divided into sympathetic (fight or flight) and parasympathetic (rest and digest) systems; utilizes different neurotransmitters.
Sympathetic Division: short preganglionic axons; cell bodies in thoracic and lumbar regions.
Parasympathetic Division: long preganglionic axons; cell bodies in brainstem and sacral regions.

Enteric Nervous System (ENS)

Extensive ganglia network regulating gastrointestinal (GI) system functions, independent of CNS input.
Contains two major plexuses: myenteric (muscle tone and contraction control) and submucosal (local secretion and absorption).
