Microscope Care & Use

• Know the rules for proper care and use of the microscope.

• Identify the parts of the microscope (ocular, objective, stage, coarse/fine focus, etc.).

• Know how to prepare a wet mount and use the microscope for viewing slides.

Cell Division

• Understand the steps of the cell cycle and mitosis.

• Mitosis: Process by which a cell divides to produce two identical daughter cells.

• Phases: Prophase, Metaphase, Anaphase, Telophase.

Tissues

• Histology: Study of tissues.

Muscle Cell Anatomy

• Sarcomere: Functional unit of muscle contraction.

• Key structures: Z disc, M line, H zone, A band, I band, actin (thin filament), myosin (thick filament).

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

Gross Anatomy of the Muscle System

• Muscle Classification: Prime movers (agonists), antagonists, synergists.

• Naming Muscles: Based on size, shape, location, number of origins, direction of fibers.

• Head and Neck Muscles: Frontalis, occipitalis, temporalis, orbicularis oculi/oris, masseter, buccinator, zygomaticus.

• Muscle Attachments: Know the action, origin, and insertion for major muscles.

EXAM 4

Neuron Anatomy

• Neurons: Cells specialized for communication via electrical impulses.

• Neuroglia: Support cells in the nervous system; types include astrocytes, oligodendrocytes, microglia, ependymal cells.

• Neuron Structure: Cell body, dendrites, axon, myelin sheath, nodes of Ranvier.

• Neuron Classification: By structure (multipolar, bipolar, unipolar) and function (sensory, motor, interneuron).

Brain Anatomy

• Cerebral Hemispheres: Frontal, parietal, temporal, occipital lobes.

• Brain Regions: Cerebrum, cerebellum, diencephalon, brainstem.

• Ventricles: Cavities within the brain containing cerebrospinal fluid.

• Cranial Nerves: 12 pairs, each with specific functions (sensory, motor, or mixed).

Spinal Nerves

• Spinal Nerves: 31 pairs, classified by region (cervical, thoracic, lumbar, sacral, coccygeal).

• Plexuses: Networks of nerves (cervical, brachial, lumbar, sacral).

• Functional Anatomy: Sensory and motor functions, reflex arcs.

Autonomic Nervous System

• Autonomic Nervous System (ANS): Controls involuntary functions; divided into sympathetic and parasympathetic divisions.

Reflexes

• Reflex Arc: Pathway mediating a reflex; includes receptor, sensory neuron, integration center, motor neuron, effector.
