Unit 1: Lecture 1 Self-study Flashcards
Plane of reference: Median (midsagittal)
divides the body into right/left halves
Plane of reference: Frontal (coronal)
divides the body into anterior/ posterior portions
Plane of reference: Transverse (horizontal)
divides the body into upper/ lower portions
Superior (cephalad) //
Inferior (caudad)
Anterior (ventral) //
Posterior (dorsal)
Medial //
Lateral
Superficial //
Deep
Proximal //
Distal
Supine //
Prone
Extension
reduces degree of acute joint angulation
Flexion
produces an acute angle at a joint
Abduction
moves away from the body
Adduction
moves towards the body
Circumduction
combination of extension, flexion, abduction, and adduction
Elevation //
Depression
Protraction //
Retraction
Tissue groups (5)
- skin
- fascia
- muscle
- bone
- fat
Skin
covers the body externally and has three layers (epidermis, dermis, hypodermis)
Fascia
(specializations include the superficial and deep layers)
Muscle
note organization from slide views and consists of skeletal, smooth, and cardiac divisions
Bone
skeleton consists of an axial skeleton (skull, spine, and thorax) and an appendicular skeleton (upper/ lower limbs)
Fat
(panniculus adiposis or hypodermis). The panniculus adiposis along with its underlying superficial membranous fascia are referred to as tela subcutanea.
Smooth muscle tissue
Location: mostly in walls of hollow visceral organs
Cell shape and appearance: single, fusiform, uninucleate; NO striations
Connective tissue components: endomysium
Contractions: involuntary, controlled by nervous system, and very slow
Cardiac muscle tissue
Location: walls of the heart
Cell shape and appearance: branching chains of cells; uninucleate, striations; intercalated discs
Connective tissue components: endomysium attached to the fibrous skeleton of the heart
Contractions: involuntary, heart as pacemaker, also controlled by nervous system, and slow
Skeletal muscle tissue
Location: attached to bones or skin (some facial muscles)
Cell shape and appearance: single, very long, cylindrical, multinucleate with very obvious striations
Connective tissue components: epimysium, perimysium, and endomysium
Contractions: voluntary, nervous system controls, and slow to fast
