Chemical Synaptic Transmission: Neurotransmitters are released from the presynaptic neuron into the synaptic cleft, where they bind to receptors on the postsynaptic neuron, causing a change in membrane potential. Signal Summation: Graded potentials from multiple synapses can summate, reaching threshold and initiating an action potential. Muscle Function: Functions of Skeletal Muscle: Responsible for voluntary movement, posture maintenance, and heat production. Muscle Structure and Packaging: Skeletal muscle fibers are bundled into fascicles, surrounded by connective tissue layers including epimysium, perimysium, and endomysium. Cardiac Muscle: Intercalated discs contain gap junctions and desmosomes, allowing for coordinated contraction and electrical coupling. Smooth Muscle: Dense bodies anchor thin filaments, allowing for contraction. Muscle Contraction: Involves the sliding filament theory, where actin filaments slide past myosin filaments, shortening the sarcomere. Excitation-Contraction Coupling: Action potentials trigger the release of calcium ions from the sarcoplasmic reticulum, initiating muscle contraction. Muscle Contraction and Relaxation: Contraction: Cross-bridge formation between actin and myosin filaments. Relaxation: Reuptake of calcium ions into the sarcoplasmic reticulum, allowing for muscle relaxation. Comparison of Skeletal and Smooth Muscle Contraction: Skeletal muscle contraction is voluntary and striated, while smooth muscle contraction is involuntary and lacks striations.

Economic integration Population and GDP of ASEAN Countries Population and GDP of ASEAN CountriesThe countries of ASEAN vary widely in population size and income level, yet nonetheless have achieved a high level of economic integration. ASEAN is considered to be one the developing world’s most successful regional economic cooperation zones. Unlike its primary counterparts in the developed world, the European Union (EU) and the United States–Mexico–Canada Agreement (USMCA), ASEAN has followed a more gradual and flexible approach to integration, accommodating the diversity of its member states. ASEAN has prioritized trade liberalization, sustainable development, and attracting foreign investment over deepening political integration or adopting a common currency. ASEAN’s economic integration efforts began with the creation of the ASEAN Free Trade Area (AFTA) in 1992, which successfully reduced tariffs between ASEAN’s first six members (Brunei, Indonesia, Malaysia, the Philippines, Singapore, and Thailand) to 0–5 percent by 2002. Vietnam, Laos, Myanmar, and Cambodia were required to sign the AFTA agreement upon joining ASEAN. Today tariffs between ASEAN countries are close to zero. In 2007 the ASEAN Economic Community Blueprint was signed in Singapore with the goal of achieving four objectives by 2015: (1) create a single market and production base, (2) become a highly competitive economic region, (3) promote equitable economic development within the region, and (4) fully integrate the region into the global economy. The AEC was implemented in 2015, although approximately 20 percent of measures toward achieving a single market remain in progress and have been deferred to a new deadline of 2025. The ASEAN-Japan Comprehensive Economic Partnership (AJCEP) was implemented in 2008, and the ASEAN-China Free Trade Agreement (ACFTA) was implemented in 2010. In 2020 ASEAN joined Australia, China, Japan, New Zealand, and South Korea in signing the Regional Comprehensive Economic Partnership (RCEP), the largest trade agreement in history.

Significant challenges remain for ASEAN’s economic integration, including pervasive nontariff barriers, restrictive investment measures, and vast disparities in GDP per capita. Domestic issues such as political instability and corruption in member states exacerbate these challenges. The COVID-19 pandemic created severe economic disruption in sectors such as industrial production and tourism; nonetheless, ASEAN coordinated a regional response to align economic recovery strategies and maintain open trade routes. Ultimately, ASEAN has demonstrated an exemplary and ongoing commitment to strengthening cooperation and integration and maximizing the region’s economic potential.
