Study Notes

Muscular Anatomy

Abductors are muscles that draw body parts, like fingers or limbs, away from the midline of the body.
Adductors, in contrast, draw body parts inward toward the midline.
The biceps are prominent muscles that contribute to the contour of the upper arm's inner and front side.

Tissues and Metabolism

Adipose tissue is specialized connective tissue that provides insulation, cushioning, and contour to the body.
Anabolism refers to the constructive phase of metabolism where larger molecules are built from smaller ones, while catabolism breaks down compounds to release energy.
Epithelial tissue serves as a protective covering on body surfaces.

Nervous System and Muscles

The autonomic nervous system controls involuntary muscles including those of glands and blood vessels.
The central nervous system consists of the brain and spinal cord, governing all bodily functions.
Motor nerves transmit impulses from the brain to muscles, leading to movement.

Cardiovascular and Skeletal Systems

The heart is a muscular organ essential for blood circulation, composed of a network that includes the left and right atria.
The clavicle (collarbone) connects the sternum and scapula, playing a role in shoulder stability.

Structural Components

The cranium is the bony case protecting the brain, while the occipital bone forms the back of the skull.
Joints are connections between two or more bones, with various types allowing different movements.
Organs are specialized structures composed of tissues, performing distinct functions within the body.

Cellular Components

Cells are the fundamental units of life, each enclosed by a cell membrane that regulates substance entry and exit.
The nucleus contains nucleoplasm and is essential for genetic information storage and cell function control.
Organelles are miniature structures within a cell, each performing specific roles necessary for cellular activity.

Other Anatomical Features

The buccal nerve affects the mouth's muscles, while the infraorbital nerve influences skin sensations in the face.
The greater auricular nerve affects skin and muscles in the face, ears, and neck.
The nasalis muscle, along with others like the mentalis, contributes to facial expressions by manipulating skin around the nose and chin.

Energetics and Growth

Metabolism is a crucial chemical process for cell nourishment and energy production, divided into anabolism and catabolism.
Mitosis is the process of cell division forming new cells, fundamental for growth and repair.

Muscle Function

Extensors are responsible for straightening the wrist and fingers, while flexors operate to bend these joints.
The epicranius covers the skull, comprising muscles responsible for scalp movement and facial expression.

Terminology and Definitions

Terms like 'insertion' describe where muscles attach to bones, while 'belly' refers to the muscle's middle part.
Histology, or microscopic anatomy, is key to understanding tissue composition and function.

These concise notes cover the core concepts and definitions related to general anatomy and physiology as outlined in the provided text.
