Major Topics and Subtopics

Introduction to Anatomy and Physiology

This section introduces the basic principles of anatomy (structure) and physiology (function) of the human body, including homeostasis.

• Anatomy: Study of body structure and organization.

• Physiology: Study of body function and mechanisms.

• Homeostasis: The maintenance of a stable internal environment.

• Example: Regulation of body temperature through sweating or shivering.

Tissues

Explores the four basic tissue types that compose the human body.

• Epithelial Tissue: Covers body surfaces and lines cavities.

• Connective Tissue: Supports, binds, and protects organs.

• Muscle Tissue: Responsible for movement.

• Nervous Tissue: Conducts electrical impulses for communication.

• Example: Skin contains epithelial tissue; muscles contain muscle tissue.

Integumentary System

Focuses on the skin and its accessory structures, such as hair and glands.

• Functions: Protection, sensation, temperature regulation, vitamin D synthesis.

• Layers: Epidermis, dermis, hypodermis.

• Accessory Structures: Hair, nails, sweat glands, sebaceous glands.

• Example: Sweat glands help cool the body during exercise.

Skeletal System

Covers the structure, classification, and function of bones, as well as bone formation and remodeling.

• Bone Structure: Compact vs. spongy bone, bone marrow.

• Bone Classification: Long, short, flat, irregular bones.

• Bone Formation (Ossification): Intramembranous and endochondral ossification.

• Bone Remodeling: Continuous process of bone renewal.

• Axial Skeleton: Skull, vertebral column, rib cage.

• Appendicular Skeleton: Limbs and girdles.

• Example: The femur is a long bone; the sternum is a flat bone.

Joints

Examines the classification and function of joints, including synovial membranes.

• Joint Classification: Fibrous, cartilaginous, synovial joints.

• Synovial Joints: Freely movable joints with a synovial cavity.

• Example: The knee is a synovial joint; the sutures of the skull are fibrous joints.

Muscular System

Describes muscle anatomy, neuromuscular junctions, muscle contraction, and muscle energetics.

• Muscle Anatomy: Structure of skeletal muscle fibers, fascicles, and connective tissue coverings.

• Neuromuscular Junction: Site where a motor neuron stimulates a muscle fiber.

• Muscle Contraction: Sliding filament theory; role of actin and myosin.

• Muscle Energetics: ATP production and usage during contraction.

• Example: Biceps brachii contracts to flex the elbow.

Nervous System

Explores the structure and function of the nervous system, including neurons, synapses, and neurotransmitters.

• Central Nervous System (CNS): Brain and spinal cord.

• Peripheral Nervous System (PNS): Nerves outside the CNS.

• Neurons: Basic functional units of the nervous system.

• Synapses: Junctions between neurons for signal transmission.

• Neurotransmitters: Chemical messengers (e.g., acetylcholine, dopamine).

• Membrane Potential: Electrical potential difference across the neuron's membrane.

• Example: Reflex arcs involve sensory and motor neurons.

Special Senses

Discusses the anatomy and physiology of the special senses, including vision, hearing, smell, and taste.

• General Senses: Touch, pain, temperature.

• Special Senses: Vision (eye), hearing (ear), smell (olfaction), taste (gustation).

• Example: The retina contains photoreceptors for vision.

Laboratory Practicals

Laboratory sessions reinforce lecture material through hands-on activities. Key practicals include:

• Lab Practical 1: Orientation terminology, tissues, skin

• Lab Practical 2: Bones and joints

• Lab Practical 3: Muscles

• Lab Practical 4: Nervous system and special senses

Key Definitions and Concepts

• Homeostasis: The process by which organisms maintain a stable internal environment.

• Ossification: The process of bone formation.

• Synapse: The junction between two neurons where communication occurs.

• Action Potential: A rapid change in membrane potential that propagates along the neuron.

• ATP (Adenosine Triphosphate): The primary energy carrier in cells.

Important Equations

• Nernst Equation (for membrane potential):

$E = \frac{RT}{zF} \ln \left( \frac{[\text{ion outside}]}{[\text{ion inside}]} \right)$

• Muscle Force Calculation:

$\text{Force} = \text{Mass} \times \text{Acceleration}$
