Chp 31-32 Flashcards
Generalist species
Species of animals that are highly adaptable to a number of environments and ways of life.
Bipedal
Walking on two legs.
Manipulative hands
The human hand can grip with strength and with fine control.
Opposable thumb
thethumbcan be moved around to touch the other fingers, which gives people the ability to grasp things.
Power grip
any carrying or grasping task where the fingers flex toward the palm
Omnivorous
Consuming both plant and animal products.
Stereoscopic color vision
The single perception of a slightly different image from each eye, resulting in depth perception.
Brain
Highly developed in humans, capable of abstract reasoning, problem-solving, tool-making, consequential thinking, and introspection.
Broca’s area
Area of the brain in humans that is highly developed, allowing humans to have complex language skills.
Language
Language,a system of conventional spoken, manual, or written symbols by means of which human beings, as members of asocial groupand participants in itsculture, express themselves.
Preadult
Of or relating to the period preceding adulthood or the adult stage of the life cycle.
Integumentary system
Considered our first line of defense Includes the skin, hair, nails, and associated glands. This is the largest organ system in the body.
Epidermis
The skin’s most superficial layer.
Dermis
The second layer of the skin, found below the epidermis.
Hypodermis
Deep subcutaneous layer of the skin.
Dermal papillae
Thick dermis found in some regions of the body that may appear uneven.
Dermatoglyphics
Fingerprint identification.
Endoskeleton
an internal skeleton, such as the bony or cartilaginous skeleton of vertebrates.
Exoskeletion
a rigid external covering for the body in some invertebrate animals providing both support and protection.
Skeletal system
consists of bones, cartilage, ligaments, and associated connective tissues.
Hematopoiesis
the production of blood cells and platelets, which occurs in the bone marrow.
Axial skeleton
Consists of 80 bones including the skull, ossicles of the ear, hyoid bone, ribs, vertebrae, and sternum. These bones form the axis of the body, providing support to the body, attachment for muscles, stabilization of the appendicular skeleton, movements associated with respiration, and protection for the brain and internal organs.
Appendicular skeleton
Consists of 126 bones that include the pectoral girdle, the arms, the hands, pelvic girdle, legs, and the feet.
Articulation
A joint and refers to a point where two bones meet.
Diarthroses
a form of articulation that permits maximal motion
Synarthroses
Immovable joints include the sutures of the skull and the gomphosis betweenez the teeth and jaw.
Amphiarthrosis
Slightly movable fibrous or cartilaginous joint.
Skeletal muscle
Responsible for movement, maintenance of posture, generation of body heat, and support of soft tissues.
Tendons
attaches muscle to bone.
Ligament
attaches bone to bone.
Fascia
A band or sheath of fibrous connective tissues, serves to cover muscles, and attaches muscle to skin.
Origin
The origin of a muscle refers to the more stationary attachment.
Insertion
The insertion refers to the more movable attachment.
Muscle action
Movement provided by a muscle.
